According to Joule's law of heating , heat produced `H = I^(2) Rt`, where `I` is current , `R` is resistance of `I` , `R` , and `t `are `3% , 4% , and 6% `, respectively , find error in the measurement of `H`.

Explanation

`H = I^(2) Rt`
:. `( Delta H)/( H) xx 100 = (( 2 Delta I)/(I) + (Delta R)/ ( R ) + ( Delta t)/( t) ) xx 100`
` = ( 2 xx 3 + 4 + 6)% = 16%`
