Questions:
1) in diagram A, how does the motor affect the level of brightness of the light bulb as the
circuit is turned on?
aſ the motor takes away the light from the bulb so that it will get dimmer
b) the motor serves as a switch for the bulb and cell
cl the motor takes away too much energy from the cell than the light bulb
d) all of the above
2) How does motor convert the electricity from the battery?
a) The motor converts the electrical energy into light energy
b) The motor converts it into sound energy
c) The motor converts the electrical energy into heat energy
d) The motor converts it into mechanical energy
3) What component of the electrical circuit do you wish to add to Diagram A to control the
flow of electricity?
a) switch
b) cell
c) battery
d) motor
4) What is the additional component in the circuit in Diagram B that is not present in
Diagram A?
a) bulb
b) cell
c) switch
d) motor
5) is the brightness of the light bulb in Diagram A the same with the light bulbs in Diagram B?
Why?
a) Yes, because their using the same number of light bulbs
b) No, because the light bulb in Diagram A is dimmer than the light bulbs in Diagram B
c) Yes, because the light of the bulb in Diagram A is being increased by the motor before it
d) No, because the light of bulb in Diagram A is brighter than the light bulbs in Diagram B
6) What do you think is the reason why Diagram B is better than Diagram A?
a) it is because the circuit in Diagram B has a switch
b) it is because Diagram B provided brighter lights than in Diagram A
c) it is because Diagram B is not using motor which is taking away so much electrical energy in the
cell
d) all of the above are correct
