Vedclass · Answer

(A) $1 \; kWh$ is the unit of electrical energy.$1 \; kWh = 1 \; 	ext{kilowatt} 	imes 1 \; 	ext{hour}$.Since $1 \; 	ext{kilowatt} = 1000 \; 	ext{watts}$ and $1 \; 	ext{hour} = 3600 \; 	ext{seconds}$.Therefore,$1 \; kWh = 1000 \; 	ext{W} 	imes 3600 \; 	ext{s}$.$1 \; kWh = 3,600,000 \; 	ext{joules}$.In scientific notation,this is $3.6 	imes 10^{6} \; 	ext{joules}$.
