Electricity

Question 1

Electric Field

Answer 1

region of space where a static electric charge experiences a force other than gravity

Question 2

Electric Field Strength

Answer 2

Force per unit charge

Question 3

Potential Difference

Answer 3

The work done in bringing a charge of on coulomb from one point to another

Question 4

Potential at a point

Answer 4

The work done in bringing the charge to the ground

Question 5

Capacitance

Answer 5

Ratio of charge on a conductor to its potential

Question 6

Current

Answer 6

The flow of charge

Question 7

Emf

Answer 7

A voltage applied to a circuit

Question 8

Ohm’s Law

Answer 8

The current flowing through a conductor is directly proportional to the potential difference across it, assuming constant temperature.

Question 9

Resistivity

Answer 9

The resistance of a cube of material of side 1m

Question 10

Joule’s Law

Answer 10

The rate at which heat is produced in a conductor is proportional to the square root of the current, given constant resistance

Question 11

The Volt

Answer 11

the potential difference between two points is one volt if one joule of work is done when bringing a charge of one coulomb from one point to another.
