What type of charges move or flow?

Negative A 100

What is the continuous flow of negative charges called?

Electric current A 200

What is a path which negative charges can flow?

Electric circuit A 300

What is the name of a unit of energy?

Electrical charge A 400

To what is a current of electricity similar?

A stream or river A 500

What type of circuit is shown in the picture below?

Simple circuit B 100

What is a circuit that has a break in the pathway of negative charges?

Open circuit B 200

What causes a circuit to be considered open?

There’s a break in the pathway so the negative charges can’t flow.

Name a device that opens or closes a circuit. B 400

switch B 400

When wiring more than one object (such as light bulbs) together, what two types of circuits can be created? B 500

Series and parallel circuits B 500

What is the name for materials that allow electricity to move easily?

Conductors C 100

What does an insulator do to electric charges?

Insulators prevent or stop the flow of electric charges.

Name three different insulators. C 300

Paper, plastic, rubber, wood, ceramics, cloth

DAILY DOUBLE DAILY DOUBLE Place A Wager C 400

What prevents people from getting shocked when touching an electric cord or plug?

The copper wire is covered with plastic that acts as an insulator.

Are ceramics insulators or conductors of electricity?

Insulators C 500

Who invented the first light bulb?

Thomas Edison D 100

Which type of light bulb produces more heat than light, gets very hot, and is expensive to use?

Incandescent bulb D 200

Name the long, thin wire coil inside an incandescent bulb that is made of tungsten.

filament D 300

What light bulb gives off ultraviolet light? D 400

Florescent light bulb D 400

Give one reason why a florescent light bulb is better than an incandescent light bulb.

Florescent light bulbs cost less to operate, produce less heat, and are good for the environment because they don’t waste energy. D 500

When a switch is turned on, you close a circuit When a switch is turned on, you close a circuit. Does this make the circuit complete or incomplete? E 100

complete E 100

What type of wire is used today because it is a good conductor of electricity?

Copper wire E 200

Name a circuit that has more than one path for electricity to follow.

Parallel circuit E 300

What causes the crackle you hear when you touch a doorknob after rubbing you feet across a carpet?

Electric discharge of static electricity

When an electrical circuit is open, is the switch on or off?

off E 500

Click on screen to continue Look at the image below. Explain the difference between image A and image B. A B Click on screen to continue

Click on screen to continue Image A is a series circuit. There is only one path for the electric charges to follow. If one bulb is removed, neither bulb will light. Image B is a parallel circuit. There is more than one path for the electric charges to follow. If one bulb is removed, the other bulb will still light. Click on screen to continue
