A current of 22 amperes flows in a heater coil whose resistance is 5 ohms. What E M F in volts is required?
The Attempt at a Solution
Not quite sure where to begin. I'm thinking the internal resistance, R, is inherent w/the circuit so EMF must be greater than the velocity calculated.
EMF=V +IR = 110 + 22x5=220 volts
Any comments here on if this is correct?
