Question

when 2A current is passing through a conductor in 10 seconds, 80 J heat is produced then find the resistance of conductor.

a) 4 omega
b) 0.2 omega
c) 2 omega
d) 0.4 omega

Explain with solution....

^_^ thanks..

Answer 1

H = I²Rt
80 =(2)²xRx10
80/10 =4R
8 =4R
R = 2 ohm

I think option C is right

hope its may work
