Question

Explain with a neat circuit diagram,how you will determine the unknown resistance using meter bridge​

Answer 1

Explanation:

A galvanometer is connected in the circuit, in such a way that its one end is connected in between the resistances X and Y. The other end is moveable and placed on the wire. A meter bridge works on the principle of Wheatstone's bridge. To find the value of the unknown resistance (Y), the circuit is balanced.
