Parallel vs Series

One of the advantages of _________ circuits is that they ensure all components in the circuit have the same voltage

as the source.For instance, all bulbs in a string of lights have the same brightness.

• open

• multiple

• series

• parallel

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit

• series circuit

• parallel circuit

• open circuit

What kind of circuit is this?

• Series

• Consecutive

• Parallel

• Training

Which circuit(s) are parallel?

• A

• A and B

• B and C

• C

In a parallel circuit, if one bulb burns out, what happens to the other bulbs?

• All other bulbs will also burn out.

• All other bulbs will become brighter.

• All other bulbs will stay lit at the same brightness.

• All other bulbs will turn off but not burn out.

In a parallel circuit, if one connection is broken, all of the connections stop working.

• True

• False

In a parallel circuit if one light bulb goes OUT; then they ALL go out. TRUE OR FALSE?

• TRUE

• FALSE

Does a break in one branch affect another branch in a parallel circuit?

• Yes

• No

• Sometimes

What type of circuit is this picture?

• parallel

• series

• open
