Match the object to its description by drawing a line between matching pairs.
motor
stores electric charge between two conducting
materials
bulb
creates light when powered and is measured in
watts
fuse
a device that can act like an electrically controlled
switch, always having three terminal pins
wire
controls the flow of current in a circuit by opening
and closing
buzzer
joins a circuit together and allows electricity to flow
battery
creates sound energy from electrical energy
resistor
creates light energy, but does not contain a filament
and produces minimal heat
transistor
converts chemical energy into electrical energy
switch
a device that prevents damage to other components
due to short circuits
light emitting diode
restricts the flow of energy
capacitor
a device used to convert electrical or chemical
energy into kinetic energy
Which piece of electrical equipment would you need in your circuit to perform these
tasks?
create noise in an electrical device
power the gears in a clock
supply a toy with electrical energy

Lawrence needs to create a circuit to use in a device that will help him when accessing
areas of the laboratory at night. Lawrence’s device will need to shed light and make
noise. Don’t forget that these pieces of equipment will not power themselves!
a
List four bits and pieces Lawrence might use to create his circuit.
b
State three energy transformations that would be occurring in Lawrence’s circuit.
