Best Answer

-- Voltage between two points

-- Resistance of the conducting path between the same two points

-- Current that flows between the two points

Answer

There are two quantities involved with Ohm's Law: potential difference and current. For a circuit to obey Ohm's Law, the ratio of potential difference must be constant. Not many circuits obey Ohm's Law. Those that do, are called 'linear' or 'ohmic' circuits; those that don't are termed 'non-linear' or 'non-ohmic'.

Ohm's law relates three quantities: voltage (V), current (I), and resistance (R). The law states that the current passing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. Mathematically, Ohm's law is expressed as V=I*R.
