Question

the armature current of a dc motor is 10 mA with a back emf of 20 V .the applied voltage to motor is 100 V . calculate the armature resistance in kilo ohms

Answer 1

A practical way to measure the winding resistance is to use the Ohm's law: Resistance = Voltage / Current. If you apply a power source to the windings and measure the voltage and current flowing through them, a simple division will yield an accurate value for the resistance
