(C) The formula for electrical energy $E$ consumed is given by $E = P 	imes t$,where $P$ is power and $t$ is time.Since power $P = \frac{V^2}{R}$,the energy formula becomes $E = \frac{V^2}{R} 	imes t$.Given values are $V = 200\,V$,$R = 80\,\Omega$,and $t = 2\,h$.Substituting these values into the formula:$E = \frac{200 	imes 200}{80} 	imes 2$$E = \frac{40000}{80} 	imes 2$$E = 500 	imes 2 = 1000\,Wh$.
