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- if one light bulb doesn't work, the others won't either

• It uses a single battery.

• if one light bulb doesn't work the others still will

Which circuit (s) are parallel?

• A- if one bulb goes out the other bulb won't work

• A and B

• B and C- If one bulb goes out, the other will still work

• C

Which one will still function if one light bulb goes out?

• A-Series

• B-Parallel

• A-Parallel

• B-Series

If I add more light bulbs to a series circuit what happens?

• The current speeds up and the lights get brighter
• The current slows down and the lights dim lower
• The current speeds up and the lights dim lower
• The current slows down and the lights get brighter

The best conductors for electricity are made of...

• wood
• plastic
• rubber
• metal
