What makes up an electric circuit?
Bulb and battery
Bulb, battery and switch
Bulb, battery and wire
Why is a battery important in an electrical circuit?
As a source of energy.
As a path for electricity to flow through.
As a connector to connect all parts of a circuit.
Why must parts of a circuit be properly connected before the bulb can light up?
To ensure that the bulb can light up.
To ensure that the battery can produce light in a closed circuit.
To ensure that electric current can flow through the closed circuit.
Look at the diagram. Why did the bulb not light up?
The bulb was fused.
The battery had not enough electric current to light up the bulb.
The switch was opened and prevented electric current from flowing through the circuit.
The diagram shows a complete circuit but the bulb did not light up. Why?
The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.
The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.
The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.
Look at the circuits in the diagram. In which circuit will the bulb be brighter?
Circuit A
Circuit B
Both circuits, the bulbs will have the same brightness.
Why electrical wiring usually are covered with a layer of plastic?
To make it look pretty
To help electricity flow along the wire
To make it safe
To add more energy
What are the two ends of a battery called?
south and north terminals
positive and negative terminals
End to end terminals
A device for making or breaking an electric circuit.
Cell
Filament
Electric switch
Find the odd one
Silver
Copper
Bakelite
The direction of current flow is taken from
negative to positive terminal
Positive to negative terminal
Both
The complete path through which an electric current is flowing is called
Open circuit
Closed circuit
Both
Thin metal wire inside the electric bulb
Fiber
Terminal
Filament
Which type of energy is stored in a battery?
chemical energy
kinetic energy
light energy
How many terminals do each cell have?
3
4
2
Why is electrical wiring usually made from copper?
Because copper is shiny
Because copper conducts electricity
Because copper is not magnetic
Because copper insulate electricity
Will the light bulbs light up in this image?
Yes, both of them will
Yes, but only the one on the right
No, neither of them will
Yes, but only the one on the left
Is this a working circuit?
Yes
No
I'm not sure, I would need to test it myself.
