Back

The measure of how much a material opposes the flow of electricity.

Front

What do most electrical conductors allow to move through them? (two words)

Back

Electric current

Front

What is a parallel circuit?

Back

The more bulbs you add, the light bulbs will stay bright.

Front

What is static electricity?

Back

Is the buildup of negative charges on an object.

Front

What is a series circuit?

Back

Has only one path for electricity to flow. The more bulbs added to a series circuit, the dimmer the bulbs will become.

Front

What is an electrical conductor?

Back

An object in which negative charges can easily pass through and conduct electricity.

Front

What is an electrical insulator?

Back

An object in which negative charges cannot easily pass through and does not conduct electricity.

Front

What happens to the brightness of bulbs in a series circuit when more bulbs are added?

Back

The bulbs will become dimmer.

Front

What happens to the brightness of bulbs in a parallel circuit when more bulbs are added?

Back

The bulbs will stay bright.

Front

What is electric current?

Back

The flow of electric charge through a conductor.
