What is the unit of electrical resistance?

Back

Ohm.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases.

Front

What is the role of a battery in a circuit?

Back

To provide the voltage needed to push current through the circuit.
