Hello there's a piecei don't understand ,on Emf calculation, I'd like to please know why we add the voltage drop across the brushes because i think the calculation using the amature circuit resistant thats given should make up for all the voltage drop in the amature circuit as the resistance in the brushes is part of the circuit

@ntuthukokunene928 yes we adding voltage drop due to the brushes when it is given or brush resistance is given.
