The heat generated in a circuit is given by Q = I2Rt, where I is current, R is resistance and t is is time. If the percentage errors in measuring I, R and t are 2%, 1% and 1%, respectively, then the maximum error in measuring heat will be : |
2% 3% 4% 6% |
6% |
Required error is 2 x 2% + 1% + 1% = 6% |
