(A) The power $P$ transmitted is $2.2 \, kW = 2.2 	imes 10^3 \, W$.The voltage $V$ is $22000 \, V$.The resistance of the line $R$ is $10 \, \Omega$.The current $i$ flowing through the line is given by $i = \frac{P}{V} = \frac{2.2 	imes 10^3}{22000} = \frac{2200}{22000} = 0.1 \, A$.The power loss in the form of heat in the line is given by $P_L = i^2 R$.Substituting the values: $P_L = (0.1)^2 	imes 10 = 0.01 	imes 10 = 0.1 \, W$.

If $2.2 \, kW$ power is transmitted through a $10 \, \Omega$ line at $22000 \, V$,the power loss in the form of heat will be ............. $W$.
