1. The problem statement, all variables and given/known data 2. Relevant equations Hello, i have been thinking, what couses a dc motor to have lets say 6volts drop across him. I was thinking that since it is just a coil it should have a verry little voltage drop, but afted testing on breadboard i figured out that it have near 6 volts. 3. The attempt at a solution So i assume that since it is rotating continuesly in a magnetic stator, that stator field inducec counter emf in to the coil and in order to pass, the motor voltage have to overcome that counter emf. Is that right?
