8V is shed across the wire resistance ( V = I × R ) which has a latest of 311mA. The motor does not care regarding the voltage, only The present. which is the principal parameter in all calculations. While we are constrained by transformers that happen to be made to offer a specified voltage, Fortuitously It is easy to work this after we know the way.
