(C) The total power $P$ consumed by two geysers is $P = 2 	imes 1.1 \, kW = 2.2 \, kW = 2200 \, W$.Given supply voltage $V = 220 \, V$.The current $I$ flowing through the circuit is calculated using the formula $I = P / V$.$I = 2200 \, W / 220 \, V = 10 \, A$.To safely operate the appliances,the fuse rating must be slightly higher than the current drawn by the circuit to prevent nuisance tripping while protecting against overcurrent.Therefore,the minimum rating of the fuse should be greater than $10 \, A$.

Find the minimum rating of fuse that can be safely used on a line on which two $1.1 \, kW$ electric geysers are to run simultaneously. The supply voltage is $220 \, V$. (in $A$)
