When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel
• series
• open
• closed

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

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.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

When a balloon is rubbed on clothes it acquires a charge by ___________.

• Induction

• reduction

• friction

• concuction

TRUE or FALSE: According to Coulomb's Law, the greater the separation of distance between two charges the greater the magnitude of the electrostatic force.

• True

• False
