Type: MCQ-numerical-Medium-Class 12
The heat produced in a long wire is characterised by resistance, current and time through which the current passes. If the errors in measuring these quantities are respectively 1%, 2% and 1%, then total error in calculating the energy produced is
A
4%
B
6%
C
4/3%
D
8%
Correct Answer
