Question

find the resistance of the conductor in which 5 ampere current flow on applying potential difference of 20V​

Answer 1

Step 1: Make circuit diagram [Refer Fig.]

Step 2: Apply KVL in loop

While applying KVL in clockwise direction, increase in voltage is considered as positive and decrease in voltage as negative.

∴ V−iR=0

Given V=20 volt,R=5Ω

⇒ i=

R

V

=

5

20

= 4 A
