Electric current

• a material through which an electric charge can move easily

• an electric charge in motion

• a material through which an electric charge moves slowly

A parallel circuit has two or more paths through which electric charges can flow, so the current will still flow if one loop is broken.

• True

• False

This type of circuit only allows electricity to flow in one circular path.

• Parallel

• Series

• Both of the above

A thin-coiled resistor that transforms electrical energy into heat and light energy.

• friction

• filament

• resistor

A resistor is an object that uses the energy in a circuit.

• True

• False

A force that acts when two surfaces rub together.

• Friction

• Filament

• Resistor
