The heat generated in a circuit is given by \( Q=I^{2} R t \), where \( I \) is current, \( R \) is resistance, and
\( \mathrm{P} \) \( t \) is time. If the percentage errors in measuring

W. \( I, R \), and \( t \) are \( 2 \%, 1 \% \) and \( 1 \% \) respectively, then the maximum percentage error in measuring heat will be \( \% \).
