Question

a current of 2A passing through a conductor produces 80J of heat in 10 seconds. The resistance of the conductor is

Answer 1

Hey there!

Given,
Current = i = 2 A
Heat = E = 80 J
Time =t = 10 sec

We know,
E = i^2 Rt
E / i^2×t = R
80 / 2^2 × 10 = R
80 / 40 = R
2 = R
or, R = 2 ohm.

Hope It Helps You!

Answer 2

   HEY THERE  

  GIVEN THAT  

Current = i = 2 A

Heat = E = 80 J

Time =t = 10 sec

   We know  

   E = i² Rt

⇒E / i²×t = R

⇒80 / 2² × 10 = R

⇒80 / 40 = R

⇒2 = R

⇒R = 2 ohm.
