1.	The heat dissipated in a resistor can be obtained by the measurement of resistance, current and time. If the maximum error in the measurement of these quantities is 1%, 2% and 1% respectively, the maximum error in the determination of the dissipated heat is
Answer» `4%` `6%` `(4)/(3)%` `2%` SOLUTION :Heat dissipated in a RESISTOR is given by `H= I^(2)Rt` `:. (DeltaH)/(H)= 2(DeltaI)/(I)+ (DeltaR)/(R)+ (Deltat)/(t)` For MAXIMUM percentage error, `(DeltaH)/(H)xx100= 2(DeltaI)/(I)xx100+ (DeltaR)/(R) xx 100+(Deltat)/(t)xx100= 2 xx 2%+ 1%+ 1%= 6%`
