Electric Fields

Question 1

Field

Answer 1

An action or force that acts at a distance.

Question 2

Electric Field

Answer 2

Electric fields are created by electric charges

(a field is a means of a force acting at a distance).

Question 3

Electric Field Strength

Answer 3

Force per unit charge acting on a positive charge E = F/Q.

Question 4

Potential Gradient

Answer 4

== Electric field strength = V/d = F/Q as V = Work-done per unit charge (V = Fd/Q).
