2A current flowing through any conductor for 10 second produces 80 joule heat.
Calculate the resistance of the conductor.​

Answer 1

Answer:

Resistance is 2 ohm

Explanation:

H = i^2 R t. => 80=2^2× R×10. => R = 80/40 =2 ohm

Answer 2

hii

given : current I=2A

time T 10sec

find: Q (charge)

I=Q/T

Q=I×T

2×10

20C

V=W/Q

work done 80J

charge= 20

v = 4V

R=V/I

=4/2

2ohm

hence, resistance is 2 ohm
