Question

33] (i)state ohms law. Derive relation between 1, V and R. Draw the graph between V and 12
(ii) What would be the new resistance if length of conductor is doubled and thickness is halved?​

Answer 1

Answer:

(1)ohms law states that potential difference V , across the 2 points of a given metallic wire is directly proportional to the current.provide it's temperature remains same.

Explanation:

$r \alpha i$

$r = vi$
