Question

if a potential difference of 10 volt causes a current of 2 ampere to flow for 1 minute how much energy is transferred

Answer 1

We have ,
Potential Difference , V = 10v
Current, I = 2A
Time, t = 1 min. = 60 s

We know that , V = W / q where W = work done and
q = Charge


I = q / t
=> q = I x t = 2 x 60 = 120 C

Now V = W / q
=> W = V x q = 10 x 120 = 1200 J
This work done = Energy tarnsferred = 1200 J
