Mini-Quiz: Direct Current (DC) Electrical Circuits

by Ron Kurtus (revised 14 August 2005)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why do they call it a DC circuit?

The electricity flows from the source around and back to the source in a circuit

Because most have a circuit breaker installed

To warn people of possible shocks

2. What happens when a light burns out in a series circuit?

The other lights remain lit

The voltage increases dramatically

The circuit is broken and all lights go out

3. How could you turn off a parallel circuit?

You can't turn off a parallel circuit

Put a switch before the parallel configuration, like near the battery

Unscrew one light bulb

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Always strive for success
