Question

A current of 2A passing through a conductor prodyces 80J of heat in 10s the resistance of the conductor?

Answer 1

I=2A
Heat=80J
t=10s
H=I^2Rt
80=2^2*10*R
80=40*R
R=2ohm

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.
