What is an open circuit?

• A circuit where the current flows continuously without any interruption

• A circuit where the current flows in the opposite direction

• A circuit where there is a break in the path of the current, causing the current to stop flowing.

• A circuit where the current flows at a higher voltage than normal

What is a closed circuit?

• A closed circuit is a circuit that does not allow any current to flow.

• A closed circuit is a path that is open and broken for an electric current to flow.

• A closed circuit is a complete and unbroken path for an electric current to flow.

• A closed circuit is a circuit that only allows direct current to flow.

In a series circuit, what happens to the current if one bulb goes out?

• The current stops flowing.

• The current increases.

• The current decreases.

• The current remains the same.

In a parallel circuit, what happens to the current if one bulb goes out?

• The current will stop flowing through all the bulbs.

• The current will increase in the other bulbs.

• The current will decrease in the other bulbs.

• The current will still flow through the other bulbs.

Which of the following is an example of an open circuit?

• Switch turned on

• Battery connected

• Light bulb turned on

• Switch turned off

What happens to the brightness of bulbs in a series circuit as more bulbs are added?

• The brightness of the bulbs fluctuates.

• The brightness of the bulbs decreases.

• The brightness of the bulbs increases.

• The brightness of the bulbs remains the same.

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

• The brightness of bulbs in a parallel circuit decreases as more bulbs are added.

• The brightness of bulbs in a parallel circuit remains the same as more bulbs are added.

• The brightness of bulbs in a parallel circuit increases as more bulbs are added.

• The brightness of bulbs in a parallel circuit fluctuates as more bulbs are added.

Which of the following is an example of a parallel circuit?

• A circuit with multiple light bulbs connected to the same power source

• A circuit with only one light bulb connected to the power source

• A circuit with no light bulbs connected to the power source

• A circuit with light bulbs connected in series
