What needs to be done so that this bulb will light?
A battery or cell needs to be added and the switch must be closed.
300
Would you expect these lightbulbs to be bright or dim when the circuit is complete?
Give a reason for your answer.
Bright, this is a parallel circuit and the current is split.

500
The electric flow of a circuit.
What is the current of a circuit?
500
As this circuit is, which lightbulbs will be on and which will be off?
X and Y will be on as it is a parallel circuit and they are making a complete circuit with the cell.
Z and Q will be off as they are in a circuit with the open switch, S
600
What device is used to measure current?
An ammeter

Current is measured in ____________ .
Amps
700
2A, as the current at the branches of a parallel circuit equal the total current that flows from the source (battery).
