Question

A resistance of 20 ohm has a current of 2 ampear flowing in it what potential difference will end

Answer 1

Answer:

Explanation:

R = 20ohms

 I = 2amp

 We know that

 V = IR  

Thus, V = 2 x 20

 V = 40V

Answer 2

Answer:

40 ohm

R=20 ohm and

I=2A

therefore by using following expression

V=IR

V=2×20

V=40v
