How is power defined in terms of energy transfer?
Power is the rate of energy transfer (energy transferred per second).
Power is the duration of energy transfer (time taken for energy to be transferred).
Power is the amount of energy transfer (energy transferred in total).
Power is the efficiency of energy transfer (useful energy transferred per second).
