Electric Current

Question 1

What are the two types of charge?

Answer 1

Static and moving

Question 2

Electric load

Answer 2

A device that transforms the electric energy into other forms of electricity
Examples: oven-heat, speakers-sound, fan-wind

Question 3

Electric curcut

Answer 3

A complete pathway for electrons that allow current to flow so electric energy works.

Question 4

How does a chemical cell work?

Answer 4

Chemical energy in a cell gives electrons on the negative terminal electric potential energy.

• electrons are attached to positive terminal
• when electrons reach the positive terminal the circuit is complete

Question 5

The 4 basic parts to a circuit

Answer 5

Source, conductor, load, switch

Question 6

Source

Answer 6

The source of electrical energy

Example: cell, battery

Question 7

Conductor

Answer 7

The wire through which current flows

Question 8

Load

Answer 8

A device that transforms the electric energy into other forms of electricity

Question 9

Switch

Answer 9

A device that can turn the circuit on or off by closing or opening the circuit

Question 10

Current electricity

Answer 10

A continuous flow of charge

-only works when there is a complete circuit for e- to flow

Question 11

How does current flow?

Answer 11

Electrons are bumped

Question 12

Current-measure of flow

Answer 12

Unit of flow for electric current is amperes (A)
