Ohm’s Law The relationship between Current through and Voltage across a conductor was first discovered by a German scientist George Simon Ohm. This relationship is called Ohm’s Law and be stated as; The Current “I” flowing through a conductor is directly proportional to the potential difference i.e. Voltage “V” across its ends provided the physical conditions (i.e. temperature, strain, etc) do …
