Vedclass · Answer

(B) One kilowatt-hour $(kWh)$ is the amount of energy consumed by an electrical device of power $1 	ext{ kW}$ in $1 	ext{ hour}$.$1 	ext{ kW} = 1000 	ext{ W} = 1000 	ext{ J/s}$.$1 	ext{ hour} = 3600 	ext{ seconds}$.Therefore, $1 	ext{ kWh} = 1000 	ext{ J/s} 	imes 3600 	ext{ s} = 3,600,000 	ext{ J}$.This can be expressed in scientific notation as $3.6 	imes 10^{6} 	ext{ J}$.
