Electric Charge and Circuits

What object would best complete this circuit?

• a paper clip

• a pen

• a battery

• piece of plastic

What kind of circuit is this?

• series

• parallel

Like charges _______ each other.

• attract

• repel

A material through which electrons (and therefore charge) move easily.

• insulator

• conductor

• static electricity

• ions

As you continue to add lightbulbs in series, what happens?

• The bulbs get brighter

• The bulbs get dimmer

• The bulbs remain the same brightness

• The bulbs explode and shards of glass get everywhere

Opposite charges _______ each other.

• attract

• repel

The force between electric charges depends on...

• both the mass and the distance between charges

• the distance between charges

• the amount of charge

• both the distance between and the amount of charge

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

A material through which electrons (and therefore charge) do not move easily.

• insulator

• conductor

• static electricity

• ions

Electrons have a ______ charge.

• positive

• negative

• neutral
