Types of Electric Circuits

What completes an electric circuit allowing current to flow?

• A non-conductive material

• An open switch

• A broken wire

• A closed switch

Which material is commonly used for conducting wires in circuits?

• Rubber

• Glass

• Copper

• Plastic

What happens if one bulb in a series circuit fails?

• Only that bulb goes out

• All bulbs go out

• The brightness of other bulbs increases

• No effect on other bulbs

In a parallel circuit, if one bulb fails, what happens to the others?

• All bulbs will go out

• Brightness of remaining bulbs decreases

• Circuit becomes open

• Other bulbs remain lit

What is the main advantage of using parallel circuits in homes?

• Less wiring is required

• All devices can be controlled by one switch

• Each device operates independently

• Failure of one device affects all others
