Electricity And Magetism

Question 1

What is Ohms Law?

Answer 1

> The potential difference across the conductor is directly proportional
to the current through the conductor provided that the
temperature remains constant.

> R=V/I

Question 2

What is Coulombs Law?

Answer 2

> The Magnitude of the Electrostatic Force exerted by one point charge (Q1) on another point charge (Q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them.

Question 3

What is an Electric Feild?

Answer 3

> An electric field is the region of space in which an electric charge experiences a force.

Question 4

What is Emf?

Answer 4

> The Maximum Energy provided by a Battery per unit charge passing through it.

Question 5

What is Power?

Answer 5

> The Rate at which Work is Done.

> P=W/^t

Question 6

What is an Electric Field at a point?

Answer 6

> The Electrostatic force experienced per unit Positive charge placed at that point.

> E=F/q
