The heat generated in a circuit is given by `Q = I^(2) Rt` , where `I` is current , `R` is resistance , and `t` 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 beA. `2%`B. `3%`C. `4%`D. `6%` |

Answer» Correct Answer - D `Q i^(2) Rt, (DeltaQ)/(Q) xx100 = (2Delta i)/(i) xx100 + (Delta R)/(R) xx100 + (Delta t)/(t) xx100` |
