  • a)
    5041 joules
  • b)
    5040 joules
  • c)
    4050 joules
  • d)
    4500 joules
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A current of 3·5 amperes passes through a resistance wire conne...
I = 3·5 amperes, V = 12 volt
t = 2 minutes = 120 seconds, W = ?
Formula : W = V·I·t
                      = 12 × 3·5 × 120 joules
                      = 5040 joules
