Electricity

Question 1

Voltage

Answer 1

Voltage is the energy supplied per coulomb

Question 2

Static electricity

Answer 2

Static Electricty is due to the electrical charge taht builds up on the surface of an insulator

Question 3

Current

Answer 3

Current is the flow of electrons in a second

Question 4

A.C. And D.C

Answer 4

Direct Current is when current flows in one direction and An alternating current is a current that continualy changes direction

Question 5

Circuit

Answer 5

Series= in one path

parallel=more than one path

Question 6

Resistance

Answer 6

Resistance is the opposite to the flow of current

Question 7

Does resistance increase or decrease in parallel?

Answer 7

When connected in Parallel the total resistance decreases

Question 8

Power

Answer 8

Energy is not created or destroyed it is changed from one type into another.
Power is measured in Watts, W

Question 9

Fuse

Answer 9

The Purpose of a fuse is to protect the flex from overheating

Question 10

Does kinetic energy increase or decrease when temp decreases?

Answer 10

Kinetic energy only decreases if temp decreases

Question 11

Voltage supply

Answer 11

V2=(R2/R1+R2)*Voltage supply or Vs

Question 12

Voltage

Answer 12

V=I*R
