Question

200 j of heat is produced 10 s in a 5 resistance. find the potential difference across the resistor​

Answer 1

Given :

heat(H)= 200j

time(t)= 10s

resistance (r)= 5ohm

Using formula H=I^2Rt;

200= I^2×10×5

200=I^2 ×50

I^2= 200/50

I^2 = 4

I= 2A

Answer 2

Answer:

Explanation:

V=?

R=5

H=200J

T=10s

H= V^2RT

200=V^2 ×5×10

V =√200/50

V=2v
