If 2.2,kW power is transmitted through a 100,Omega line at 22,000,V, the power loss in the form of heat will be ............. W

Q: If $2.2\,kW$ power is transmitted through a $100\,\Omega $ line at $22,000\,V,$ the power loss in the form of heat will be ............. $W$

b (b) $P = Vi$ $ \Rightarrow $ $i = \frac{{2.2 \times {{10}^3}}}{{22000}} = \frac{1}{{10}}A$ Now loss of power $ = {i^2}R$$ = {\left( {\frac{1}{{10}}} \right)^2} \times 100$ = $1\, W$
