The coil of a DC motor has a resistance of 2.0 ohms. The motor is runned by a battery of 12 V and an internal resistance of 0.5 ohms.
a) Calculate the current at the moment the motor is started
b) Calculate the current when the motor is running at 600 RPM , when there is an induced counter EMF of 10 V in the coil.
I = E / R
The Attempt at a Solution
a) is already solved I = 24 A
help with b), please
