Vedclass · Answer

(A) We know that $1$ unit of electrical energy is equal to $1 	ext{ kilowatt-hour (kWh)}$.$1 	ext{ kWh} = 1 	ext{ kW} 	imes 1 	ext{ h} = 1000 	ext{ W} 	imes 3600 	ext{ s} = 3.6 	imes 10^6 	ext{ J}$.Given that the household consumed $250$ units.Therefore,total energy in joules $= 250 	imes 3.6 	imes 10^6 	ext{ J}$.$= 900 	imes 10^6 	ext{ J}$.$= 9 	imes 10^8 	ext{ J}$.Hence,the energy consumed is $9 	imes 10^8 	ext{ J}$.
