• Conductor

The force that pushes the electricity through a circuit is called...

• Resistance

• Voltage

• Switch

• Current

The flow of electricity through a conductor is called...

• Current

• Voltage

• Resistance

• Switch

The best conductors for electricity are made of...

• wood

• plastic

• rubber

• metal

What slows down the flow of electricity in a circuit?

• Resistance

• Current

• Voltage

• Source of electric current

In a closed circuit, how does battery voltage affect current?

• As voltage increases, current increases.

• As voltage increases, current decreases

• Voltage has no affect on current.

• If voltage exceeds current, a short circuit circuit will develop.

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C

• Point B to Point C

• Point A to Point D

• Point B to Point D

This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery

• the switch gives energy to the battery

• the wires are cooled by the surrounding air

• electricity can flow in a complete path

Which of the following can work as an energy source?

• Battery

• Light Bulb

• wire

• all of them

As the resistance of a circuit increases, the current will...

• increase

• decrease

• stay the same

• none of the answers
