The current flowing through a conductor is exactly proportional to the potential difference applied across its ends, according to Ohm’s law, assuming that the physical parameters and temperature of the conductor stay constant. Ohm’s law is the name for this.
State Ohm’s law and draw a neat labelled circuit diagram containing a battery, a key, a voltmeter, an ammeter, a rheostat and an unknown resistance to verify it.
