A current of (2.5±0.05) A flows through a wire and develops a potential difference of (10±0.1) volt. Resistance of the wire in ohm, is
Calculate the potential difference across the ends of a wire with resistance 2 ohms when a current of 1.5 A passes through it.
The resistance of a conductor is said to be 1 ohm if
When a potential difference of 2 V is applied across the ends of a wire of 5 m length, a current of 1 A flows through it. Calculate the resistance across the ends of the wire if its length is doubled.
