Answer 1

Question:

200J of heat is produced 10s in a 5 ohm resistance. Find the potential difference across the resistors.

Answer:

I = 2A

Explanation:

Given => heat(H)= 200j

               time(t)= 10s

               resistance (r)= 5ohm

By , Using formula H=I^2Rt;

200= I^2×10×5

200=I^2 ×50

I^2= 200/50

I^2 = 4

I= 2A

Hope you understand.
