Metal is used to make electrical wires because_______.

It allows an electric current to freely flow.

It slows electric currents from flowing.

This circuit does not work because…

the batteries are facing each other

the bulbs are not connected properly

two batteries are not powerful enough

there is a break in the circuit

This circuit does not work because…

there is a break in the circuit

the bulbs are not connected properly

the single battery is not powerful enough

does not light due to a short circuit

does not light as the cells push against each other

may blow as it is in two circuits

The diagram shows a complete circuit but the bulb did not light up. Why?

The plastic spoon is an insulator of electricity and prevented electric current from flowing through the circuit.

The plastic spoon is not connected properly and prevented electric current from flowing through the circuit.

The plastic spoon is a conductor of electricity and prevented electric current from flowing through the circuit.

Look at the circuits in the diagram. In which circuit will the bulb be brighter?

Both circuits, the bulbs will have the same brightness.

State one advantage of bulbs arranged in parallel arrangement in a circuit.

When one bulb fused the other can still light up.

Reduce the amount of electric current used for both bulbs.

Both bulbs in a parallel arrangement in circuit will share the electric current produced by the battery.

What is one problem with using a series circuit?

If one goes down, they all go down!

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

The same current flows through all three light bulbs.

The electrical current is divided between the three light bulbs.

What does the resistance of a wire tell you?

How tough it is for electrons to flow through it.

The speed of electron flow through it.

The amount of energy given to the electrons.

The amount of energy taken away from the electrons.

If the middle bulb goes out, _______

The other bulb's brightness stays the same

In a parallel circuit

There are 2 or more paths for current to flow

All devices receive the same current

All devices always go on and off together

Each device operates with a different voltage

What is the function of a battery in a circuit?

Push the electrons around the circuit and give each electron a share of energy

Push the electrons around the circuit

Give each electron a packet of energy

When an extra bulb is added to a series circuit, the original bulb gets dimmer. This is because...

The extra bulb created higher resistance and lower current

The extra bulb increased the current and increased the resistance

The extra bulb lowered the resistance and lowered the current

The extra bulb lowered the resistance and increased the current
