The circuit stops working.
The resistance of the circuit decreases.
The circuit produces less light.
What would you expect to happen if you add a buzzer to the circuit?
The buzzer will produce a sound when the circuit is complete.
The buzzer will light up like a bulb.
The buzzer will cool down the circuit.
The buzzer will stop the flow of electricity.

104
87
120
95
Murad is investigating how increasing the number of cells in a circuit will affect the brightness of the bulbs. Increasing the number of cells in a circuit will:
make the bulbs brighter
make the bulbs dimmer
have no effect on the bulbs
cause the bulbs to stop working
What effect does increasing the voltage in a circuit have on the brightness of a bulb?
The bulb becomes brighter.
The bulb becomes dimmer.
The bulb does not light up.
The brightness of the bulb does not change.
Which variable should be kept constant when investigating how the number of bulbs affects the brightness in a circuit?
The color of the bulbs
The voltage of the battery
The length of the wire
The number of bulbs

What is the difference between a cell and a battery?
A cell is just one source of electricity, while a battery is made of two or more cells joined together.
A cell and a battery are the same thing.
A cell stores electricity but a battery cannot.
A battery is just one source of electricity, while a cell is two batteries or more joined together.
