Series and Parallel Circuit

In a series connection, why do remaining bulbs not light up when one bulb is taken out of its holder?

• The path of electric current was renewed.

• The other bulbs will not light.

• The path of electric current became incomplete.

• The other bulbs were burnt out.

What will happen to the other bulbs in a parallel connection when one bulb is removed?

• The other bulbs will no longer light.

• The other bulbs will still light.

• A few bulbs will no longer light.

• few bulbs will light.

What will happen to the other bulbs in a series connection when one bulb is removed? The other bulbs will ________________________.

• have bright light and few bulbs will light.

• not light

• have a dim light

• light

Mary Ann noticed that a set of ten bulbs in her Christmas tree lights did not light up when it was turned on. What could be a probable cause of this?

• Small bulbs are used.

• Small wires are used.

• There are bulbs in the strand.

• There is one defective bulb in the set.

This type of circuit is a _________.

• series circuit

• parallel circuit

• simple circuit

Bulbs that are connected one after the other in one chain is an example of _______.

• Series circuit

• Parallel circuit

• Simple circuit

A series circuit has light bulbs with different loops. Thus, each bulb is a part of a different circuit.

• TRUE

• FALSE

In a parallel circuit, when one bulb is loosened, taken or burned out, the other bulbs still light up.

• TRUE

• FALSE

In a series circuit, electric current flows through a single path, so when one bulb is loosened or busted, all the other bulbs in this circuit will not light anymore.

• TRUE

• FALSE

Which of the following measures can prevent fire caused by electricity?

• Avoid walking under low dangling wires.

• Touch a switch with dry hands.

• Have a regular inspection of electrical cords

• Do not leave sockets empty.
