relationship between potential difference and current was given by

Options

A. George Simon Ohm.
B. Alessandro Volta
C. Michael faraday
D. Nikola tesla

Answer

a

Explanation

In 1827, a German physicist Georg Simon Ohm (1787-1854) found out the relationship between the current I, flowing in a metallic wire and the potential difference across its terminals. The po-tential difference, V, across the ends of a given metallic wire in an electric circuit is directly pro-portional to the current flowing through it, pro-vided its temperature remains the same. This is called Ohm’s law.
