Question

1. Which law is proved in the experiment of electric current, potential difference and electric
resistance ? explain it.​

Answer 1

An electric circuit consisting of a 0. 5 m long nichrome wire X Y, an ammeter, a voltmeter, four cells of 1. 5 V each and a plug key was set up. (i) Draw the electric circuit diagram to study the relation between the potential difference maintained between the points ′ X ′, and ′ Y ′, and the electric current flowing through X Y.
