Question

The heat generated in a circuit depends upon the resistance, the current and the time for which the current flows. If the errors in measuring the resistance, current and time are 2%, 3% and 1% respectively, the maximum error in measuring the heat is

Options:

Answer:

D

Solution:

% error in $H = 2 \times 3 % + 2 % + 1 % = 9 %$ .
