n electrical heater is connected to a constant 250-V sourceand absorbs 1000W. Subsequently, the heater is connected to a constant 220-Vsource. What power does it absorb from the 220-V source? What is the resistance of the heater? since we are provided with a voltage of 250V and a power of 1000W, why couldnt I use p=vi to solve for i, then use the same i to find the power absorbed by the 220-V source?
