Electricity

Question 1

Internal resistance

Answer 1

The opposition to flow of charge within a battery

Question 2

Coulomb’s law

Answer 2

The electrostatic force between 2 stationary charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them

Question 3

Electric fields

Answer 3

A region around an electric charge where another charge will experience an electrostatic force.
The direction of the electric field at a point is the direction that a positive test charge would move if places at that point.

Question 4

Ohms law

Answer 4

The potential difference across 2 points in a conductor is directly proportional to the current in the conductor provided the temperature remains constant.

Question 5

Current

Answer 5

Rate of flow of electricity charge

Question 6

Resistance

Answer 6

Opposition to flow of charge through a conductor

Question 7

EMF

Answer 7

Maximum energy that the battery supplies per coulomb charge

Question 8

Potential difference

Answer 8

Energy used per column charge by the components between 2 points in the external circuit.

Question 9

External resistance

Answer 9

Total resistance of all components connected in the circuit

Question 10

Electric field at a point

Answer 10

The electrostatic force experienced per unit positive charge place at that point

Question 11

Power

Answer 11

The rate at which work is done
