Electics

Question 1

Coulomb’s law

Answer 1

Two point charges in free space or air exert a force on each other. The forces is directly proportional to the product of the charges and inversely proportionate to the square of the distance between the charges

Question 2

Electric field point

Answer 2

The force per unit positive charge

Question 3

Potential difference

Answer 3

The work done per unit positive charge

Question 4

Current

Answer 4

The rate of flow of change

Question 5

Ohms law

Answer 5

Current through a conductor Is directly proportional to the potential difference across the conductor at constant temperature

Question 6

Resistance

Answer 6

The materials opposition to the flow of electrical current

Question 7

Emf

Answer 7

The total energy supplied per coulomb of charge by the cell

Question 8

Electrical field

Answer 8

A region of space in which an electric charge experiences a force. The direction of the electric field at a point is the direction that a positive test charge would move if placed at that point
