Vedclass · Answer

For power transmission power loss in line ${P_L} = {i^2}R$

If power of electricity is $P$ and it is transmitted at voltage $V$, then $P = Vi$ $ \Rightarrow $  $m = 6.56\,g/s\,$

${P_L} = {\left( {\frac{P}{V}} ight)^2}R = \frac{{{P^2}R}}{{{V^2}}}$ $ = \frac{{2.2 	imes {{10}^3} 	imes 2.2 	imes {{10}^3} 	imes 10}}{{22000 	imes 22000}} = 0.1\,W$

If $2.2\, Kwatt$ power is transmitted through a $10\, ohm$ line at $22000\, volt$, the power loss in the form of heat will be ............. $watt$
