Question

The heat produced by the passage of current through a resistor is:

a: H=I²Rt
b: H=IR²t
c: H=I/Rt
d: H=I²/Rt​

Answer 1

Explanation:

According to Joule's law of heating, heat produced H=l

2

Rt, where I is current, R is resistance, and t is time. If the errors in the measurement of I,R and t are 3%,4% and 6%, respectively, find error in the measurement of H

Answer 2

Answer:

option a is the answer
