Electricity Review

What transforms electrical energy to radiant energy?

• light bulb

• wire

• battery

Which of the following is not a conductor?

• metal nail

• paperclip

• rubber band

• dime

I built a circuit with a battery and light build. I didn't have any wire, so I used strings instead. Why did the light bulb not turn on.

• The string is the wrong color

• the string is too long

• metal wires are good insulators of electricity, but string is not

• metal wires are good conductors of electricity, but string is not

Examine the circuit below. Which item could you connect to the wires at Point A and Point B to make the light bulb shine?

• Plastic Straw

• Rubber Band

• Paper clip

• piece of paper
