Front

What happens when batteries are stacked up?

Back

They make higher voltages.

Front

When resistance is low, what happens to current?

Back

Current flows easily.

The flow of electric charge, typically measured in amperes.

Front

What is a conductor?

Back

A material that allows electric charges to flow through it easily, like copper.

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in ohms.
