Electricity – Background
Electricity has changed the way of life of everyone on Earth. In 1879, American
inventor Thomas Edison was finally able to produce a reliable, long-lasting electric light
bulb. With this invention, he changed the world. In only a year after that, many cities
around the world started building power stations that generated electricity for home
use. Fast forward almost 150 years, we use electricity in many different ways.

Electricity is the greatest invention in history because it changed the world. Lighting,
refrigeration, and air conditioning are the three things that most people in developed

When an electrician is planning the circuits they will use, they often draw them out
beforehand. They use a line for the wiring, and the following symbols for what they will
include in their circuit. A motor is any electrical device that changes electricity into
motion. A fan is an example of a motor. A lamp or light is commonly used as well as all
houses need light.

Why Do We Need To Use A Switch?
When we use electricity, we are using electrical circuits. In order to prevent using too
much electricity, we need to be able to turn off an electrical circuit. To turn off a light
switch, we pull the toggle switch down. This will stop the electrical circuit that runs to a
certain lightbulb from working.
What Is A Switch?
A switch acts as the on/off switch for a circuit. When you open
a switch, you turn off the circuit, as the flow of electricity
cannot continue along the opened switch. When you close the
switch, you have connected the conducting material to the rest
of the circuit so that the electricity can flow through the
circuit. When you look at the picture, you can see that the first
circuit has a closed switch that allows the electricity to flow through the switch. The
opened switch stops the flow of electricity, as it does not connect to the rest of the
circuit. Therefore, the light does not work with an opened switch.

What is a Burglar Alarm?
People can install burglar alarms in their houses to detect if someone is breaking
into their house. If you put a burglar alarm on the exterior doors or windows to
your house, anytime the door or window opens, the alarm will sound.
How Burglar Alarms Work
A burglar alarm can be a very simple electrical circuit that works using a switch.
All you need to do is setup a circuit with a buzzer, switch, and a power source.
When the switch closes, the buzzer sounds.
Making a Burglar Alarm
1. Grab a piece of wood or sturdy
cardboard, battery, 5 wires, buzzer,
string, and a switch.
2. Glue or use electrical tape to connect
the battery and buzzer to the wood
(figure 1).
3. Connect the battery to the buzzer to
test the alarm. If it works, proceed to
step 4.
4. Add the switch into the circuit. When the
switch is closed, the buzzer will sound.
Test it out, but then keep the switch
open. (figure 2)
5. You will use a small piece of cardboard to
keep the switch open. Place the
cardboard between the closed switch.
When you pull the cardboard out, the
switch should close, and the alarm should
sound. (Figure 3)
6. Attach a piece of string to the small
piece of cardboard. When the string is
pulled, the cardboard should move, which
will close the switch. When the switch
closes, the buzzer should sound!
7. Your burglar alarm is complete! Attach
the string to something you don’t want
taken. When someone takes it, the string
pulls the cardboard, and the alarm will
sound. You could attach the string to a
closed window, a door, or anything you
don’t want moved! Maybe you’ll catch a
pencil thief!

Power Sources
When we create a circuit to power a component, like a light, we need a
power source to generate the flow of electricity. In class, we commonly
use a battery to generate electricity. When you plug something into a wall,
you are getting electricity generated from spinning turbines that can provide
an almost endless amount of electricity.
Batteries
A battery is a device that stores chemical energy and converts it to
electrical energy. Inside a battery, a chemical reaction between different
chemicals like acid, lead, nickel, lithium, and alkaline produce a flow of
electrons from the negative side to the positive side. The
electrons go out of the positive side of the battery, and then
through the electrical circuit, and then back in the battery. A
battery will “die” when the chemicals inside the battery can no
longer produce the flow of electrons.
Battery Power Affecting a Circuit
Most AA and AAA batteries have the same voltage (1.5 volts). Voltage is a unit
of electricity that tells us how much electricity a power source can
generate. When you hook up a battery to a light in a circuit, the light will
receive all 1.5 volts. If you hook up 3 lights, each light will receive 0.5 volts. A
typical household lightbulb is designed to work with a voltage of 120 V. This
means a normal battery cannot power a large light. Luckily, our homes have
electrical circuits that generate 120 volts.
When we add lights or motors to a circuit, our power source needs to
be able to handle the additional components. We may find that when we add a
small light to a circuit, the battery’s voltage will not be strong enough. The
result may be that the lights in the circuit get dimmer, or they may flicker
on and off. When a fan doesn’t get enough voltage, the fan may slow down,
or it may not work at all.

On the left, a parallel circuit with 3 light bulbs. On the
right, a series circuit with 3 light bulbs.
How to Improve a Circuit
There are two simple ways to improve a circuit. You can change the wiring to
make the circuit run more efficiently, or you can add more voltage by using
another battery.
Changing the Wiring
One way to improve a circuit is to change the way the circuit is wired. If you use a
parallel circuit versus a series circuit, the voltage will be spread out more
efficiently. Look at figure 1 to see the difference between a series and a parallel
circuit.
In a series circuit, the flow of electricity has only one path. In figure 1, the
path starts at the battery, and goes through the 3 light bulbs. Each of these lights
will receive 0.5V of electricity and will be dimly lit. With a parallel circuit, there are
multiple paths for the electricity. In figure 1, the electricity has 3 different paths
through each of the lightbulbs. Each lightbulb will receive 1.5V from the battery. This
means the lights will all be bright. The downside is the battery will drain faster. A
downside of using a series circuit is that if one lightbulb goes out, the flow of
electricity stops at that broken light.
Adding a Battery
Another option to improve a circuit is to add more voltage. To do this, you can add
another 1.5V battery. This will brighten the light or make the fan run better as the
components are getting more electricity.
If you added 4 batteries to this circuit, you would have a total of 6 volts. In a
series circuit, all of the lights will become brighter as they will all receive 2V. These
lights will be even brighter than in a parallel circuit with 4 batteries, because in the
parallel circuit, the batteries will still only get 1.5 volts. The benefit of the parallel
circuit is that the circuit will last 4 times longer with four batteries.

2. A circuit with one switch and 2 motors (fans) that are turned on.
The battery is sending electricity to the closed switch. The

1. If a circuit with two light bulbs wasn’t strong enough to keep the bulbs lit, how could you improve the circuit?
You could add another battery/power source to increase the voltage in the circuit. You could also make a parallel
circuit by allowing the voltage to take two different paths to the lights.
2. Why is it important for switches to be used in circuits?
So that we can turn off the circuit when we don’t need the electrical device working. A light is an example that
we don’t need all the time.
3. What electrical devices do we use at home and at school? Name 2 for school and home use.

Long Answer Questions

How would you build a burglar alarm using an electrical circuit?
You need a buzzer, switch, wires, and a battery. You hook the battery up to a switch and a buzzer. When the
switch is closed, the buzzer will sound. Put a piece of cardboard inside the switch so that it is kept open. Then
attach a string to the cardboard so that when the cardboard is pulled, the switch closes and the buzzer sounds.
Now you can attach a string to something you don’t want moved, like a pencil or a closed window/door.
