Question

plzzzzzz.......solve this.........​

Answer 1

(ii) Since, the graph is straight line passing throgh the origin, so current is directly proportional to the potential difference.

Hence, the ratio V/I remains constant.

From graph,

when V=1.5 V

I= 0.6 amp

so, V/I = 1.5/0.6 = 2.5 ohm

For p.d. 0.8, 1.2 and 1.6 V, the value of V/I ratio remains the same, i.e, 2.5 ohm.
