- This power is also equal to rate of energy transfer from battery to device.
- Applies to electrical energy transfers of all kinds.
- Apply only to the transfer of electric potential energy to thermal energy in a device with resistance.
- P=iV is true for the battery pumping charges through any device.
- If the device follows Ohm’s law (i.e., a resistor), then V=iR or i=V/R and
