Science - Worksheet 3

The flow of electricity through a conductor.

• Circuit

• Series circuit

• Conductor

• Electric current

- In a series circuit if one lightbulb goes out, the other lightbulbs will remain lit.           

• True

• False

- A lightbulb is an example of a resistor.                                                                                          

• true

• false

- Like batteries, generators are a voltage source.                                                                         

• Ture

• False

3- In power plants other forms of energy are transformed into electricity.                          (          )

2- When the switch is closed the electric current cannot flow around in a circuit.          (                )

Your home has a collection of electric circuits hidden in the wall.

- Using the motor to produce electricity instead of motion makes it a ………………….

• magnet                          

• generator                

• switch                                  

• resistor

An electric circuit that produces a magnetic field is known as:

• electromagnet                     

• series circuit                               

• short circuit                      

• circuit diagram

A path that has little or no resistance that connects two ends of an electric source.

It can damage appliances or start fires.

• Parallel circuit                     

• series circuit                                

• short circuit                      

• circuit
