What is voltage?

• the amount of push the electrical source supplies to the circuit

• how much a given device resists the flow of electric current

• flow of electric charge

• none of the above

What kind of circuit is this?

• Series

• Consecutive

• Parallel

• Training

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.

Electrical lights will not come on unless their electrical circuit is a --

• parallel circuit

• series circuit

• closed circuit

• short circuit

What is a switch's function in a circuit?

• to make the current hotter or colder

• turn on and off the flow of current

• the pathway that current flows

• to add more power to the circuit

An object through which electrons can easily flow is called a(n) ___________.

• Conductor

• Insulator

If a string of Christmas lights are wired in series, what will happen if one bulb burns out?

• All the lights will go out.

• Only the burnt out light will go out.

• Every other light will go out.

• only the first and burnt light will go out.

If a string of Christmas lights are wired in parallel, what will happen if one bulb burns out?

• All the lights will go out.

• Only the burnt out light will go out.

• Every other light will go out.

• only the first and burnt light will go out.
