Question

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
(1) 4%
(2) 6%
(3) 4/3%
(4) 8%​

Answer 1

Answer:

the answer is 4%. ok
