The heat dissipated in a resistance can ...

The heat dissipated in a resistance can be obtained by the measurement of resistance, current and time. If the maximum precentage error in the mesurement of these quanties is `%,2% and 1% ` respectively. The maximum percentage error in the determination of the dissipated heat is -

A

`4%`

B

`6%`

C

`4//3%`

D

`2%`

Text Solution

Verified by Experts

The correct Answer is:
B
`H=I^(2)RT`
`(DeltaH)/(H)xx100=(2DeltaI)/(I)xx100+(DeltaR)/(R)xx100+(DeltaT)/(T)xx100`=
`" " =2xx2+1+1`
`" " 6%`
