Question

The percentage error in the measurement of current resistance and and time 2%, 4% and 7% respective when current passes through a wire of resistance R for time t calculate the percentage error in the measurement of head produce of a wire

Answer 1

Answer:

Heat Produced = I²Rt

Now since the ..

% error for I = 2%

% error for R = 4%

% error for t = 7%

Therefore the

% error in heat produced

= 2(2%) + 4% + 7%

= 15 %
