Question

a source of EMF 15v supplies a current of 2A for 6min how much energy is provided in this time?

Answer 1

Heat energy = I^2 × R × t = (I × R) × I × t = V × I × t

Here, I = current

R = resistance

t = time (in seconds)

V = potential difference

Therefore, answer = 15 × 2 × (6 × 60) = 30 × 360 = 10800 J

Answer 2

The answer

I hope this is helpful to you
