What characterizes a series circuit?

Back

In a series circuit, the same current flows through all components.

Front

What happens to light bulbs in a series circuit as more are added?

Back

The bulbs get dimmer as more are added.

Front

What is required for a circuit to work?

Back

A closed circuit requires an energy source.

Front

What happens if one bulb goes out in a series circuit?

Back

All other bulbs also go out.

Front

What is a parallel circuit?

Back

In a parallel circuit, the current is divided among multiple paths.

Front

What happens to the brightness of bulbs in a parallel circuit when more are added?

Back

The brightness of each bulb remains the same.

Front

What is the effect of adding more resistors in series?

Back

The total resistance increases.

Front

What is the effect of adding more resistors in parallel?

Back

The total resistance decreases.

Front

What is the role of a switch in a circuit?

Back
