Electricity

Question 1

Terminal pd def

Answer 1

The pd across the terminals of a power source.

Question 2

Resistance def

Answer 2

A measure of how difficult it is for current to flow through the material.

Question 3

Potential divider def

Answer 3

A method of splitting a pd, by connecting two resistors in series.

Question 4

Internal resistance def

Answer 4

The resistance to flow of charge within a source.

Question 5

Ohmic conductor def

Answer 5

A conductor for which the current flow is directly proportional to the pd across it, when under constant physical conditions.
