Ohm's Law states that the current flowing through a conductor is directly proportional to the potential difference applied across it, provided which key condition remains constant?
A.
The exact time of day
B.
The colour of the conductor
C.
The temperature of the conductor
D.
The atmospheric pressure surrounding the conductor
Electrical resistance is defined as the ratio of potential difference to electric current, mathematically expressed as R = V/I, and is best understood as a measure of:
A.
A conductor's opposition to the flow of electric current through it
B.
A conductor's ability to store electric charge
C.
The rate of heat generation in a conductor
D.
The total electrical energy dissipated by a conductor
