The heat generated in a circuit is dependent upon the resistance, current and time for which the current is flown. If the error in measuring the above are 1%, 2% and 1% respectively, then maximum error in measuring the heat is

Explanation

Heat `H=(i^(2)RT)/(J)`
Maximum error in measuring the heat
`(DeltaH)/(H) xx 100=2(Deltai)/(i) xx 100+(DeltaR)/(R) xx 100+(DeltaT)/(T) xx 100`
Here J is a constant
Given that
`(DeltaR)/(R) xx 100=1%,(Deltai)/(i) xx 100=2%,(DeltaT)/(T) xx 100=1%`
`(DeltaH)/(H) xx 100=(2 xx 2)+1+1=4+1+1`
Maximum error in heat=6%
