How Electricity Works.






Electricity is a flow of electrons.
A circuit will not work if there is a break
in it.
The electrons can not flow.
An electric current flows between two
points because there is a difference in
voltage. (“energy level”)
The positive terminal of a battery is at a
High Voltage level.
The negative terminal is at a
Low Voltage level.
An Electric current behaves
like the ball on the piece of
wood shown below.
The current will flow from high
to low just like the ball.
What happens if both children
raise their ends?
Technical Vocabulary
• Electrons
• Circuit
• Output
• Voltage (energy level)
• On / High / +
• Off / Low / • Time
Using Electricity
worksheets.
You will have completed the Using
Electricity worksheets with the
Electronics Kits.
 Now have a look at Using Electricity 5.
 Make sure you have the “Working
away from the computer sheet.”

Setting up Control
Console
You will need a clear desk near to a
plug socket.
 Plug in the power lead to the Console.
 Plug into the wall power socket.
 The Console will make a noise when it is
turned on.(Do not turn it on until you
have connected your outputs.)
When you have finished do not take the
lead from the console just turn off the
wall socket.

Connecting your circuit
• Connect one red plug with crocodile clip on,
to OUTPUT 1. Use a screwdriver to tighten.
• The second to the green socket next to it.
• Avoid unplugging these once they are
connected as they will break if not carefully
removed.
SAFTEY FIRST




DO NOT connect an external power
supply (mains or battery) to any of the
Console terminals.
DO NOT connect a Red Output directly to
a green Ground Terminal.
DO NOT connect a Red Output directly to
another Red Output.
DO NOT be responsible for breaking the
equipment.
Replacing the battery.
Remove the battery and connect the
crocodile clips to the metal studs.
Turning the bulb on.
Instead of typing the instructions
into a computer, we are keying
them into the Control Console.
 Start with the OUTPUT you want to
control.Then select either: HIGH/+ (ON)
 LOW/- (OFF)

Then you need to say how
long for.
Time
 Then a length of time.
 1= 1 tenth of a second.
 10 = 1 second.


e.g.
OUTPUT
1
H/+
10
Next you can add another
circuit.
Remember to key in
the correct OUTPUT!
Key in instructions to first turn on
your light bulb, then your fan.
We are going to make an
Advertising Board using an
Electric Circuit. We are going to
include three factors.
 Light.
 Colour
 Movement.
Planning and making your
board.
•Either lay a piece of paper
over your circuit and mark
where you need your holes
•Or use the planning sheet.
