Electrical Fields

Question 1

Define electrical field strength:

Answer 1

Electrical field strength refers to the force per unit positive charge.

Question 2

Define an electrical field:

Answer 2

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

Question 3

State Coulomb’s Law:

Answer 3

Coulomb’s Law states that two point charges in free space or air exert forces on each other. The force
is directly proportional to the product of the charges and inversely proportional to the square
of the distance between the charges.
