Front

What is the main difference between a series circuit and a parallel circuit?

Back

A series circuit has only one path for current, while a parallel circuit has multiple paths.

Front

What is the role of a resistor in a circuit?

Back

To limit the flow of electric current.

Front

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

Back

The total resistance increases.

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 function of a circuit breaker?

Back

To protect the circuit from overload by interrupting the flow of current.
