Q. 73.7( 33 Votes )

An electric circu

Class 10th Lakhmir Singh & Manjit Kaur - Physics 1. Electricity

Answer :

(i)

(ii) From graph we find that current values corresponding to potential difference of 0.8V, 1.2V and 1.6V respectively are 0.3 A, 0.45A and 0.6A.

From these values we conclude that ration V/I is a constant i.e., V α I. It means that Ohm’s law is being followed.

(iii) The resistance of the wire is equal to the ratio of potential difference applied and the current passing through it.
