Which is NOT true of a parallel circuit?

• Electrons can travel in more than one path in a parallel circuit.

• In a parallel circuit, the current is divided between the different paths.

• When one bulb is broken in a parallel circuit, the circuit will no longer allow electrons to flow.

• Voltage is the same across all paths in a parallel circuit.

Which is true of a series circuit?

• Electrons can travel in more than one path in a series circuit.

• In a series circuit, the current is divided between the different paths.

• When one bulb is broken in a series circuit, the circuit will no longer allow electrons to flow since there is only 1 path.

• Voltage is the same, total voltage of the battery, across all paths in a series circuit.

In the circuit shown below, when the switch is closed, all of the light bulbs are lit. Which light bulbs will remain lit when the switch is opened, as shown in the diagram?

• Only Bulb 1 will remain lit.

• Only Bulb 1 and Bulb 3 will remain lit.

• Only Bulb 1 and Bulb 2 will remain lit.

• None of the bulbs will be lit since the switch is open.

What is a circuit?

• A circuit is a closed loop of conductors through which an electrical current can flow.

• A circuit is an electrical component that provides electrical resistance.

• A circuit is the potential energy per unit charge, depends only on the location and the charge within the electric field.

• A circuit is the amount of energy needed to move a charged particle from one point to another in an electrical field.
