Q. What is a power?

Answer:

That seat of EMF" reply is SO wrong. Not merely is the rate of charge delivery not power but a seat of EMF doesn't deliver charge. A seat of EMF a battery or else a power supply maintains a potential difference in a circuit which makes it so that charge that is already in the circuit undergoes some motion but a seat of EMF should not be thought of as a charge delivery device.
