Front

What is a conductor?

Back

A material that allows electricity to flow through it easily.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, allowing multiple paths for current.

Front

What happens to the current in a series circuit when more components are added?

Back

The total resistance increases, and the current decreases.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.
