working of DC motor
Answers
Explanation:
A DC motor is an electrical machine that converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force....
Explanation:
Working: when the coil star rotating with arm moving up and moving down,then by Fleming right hand rule, the direction of induced current is through in the circuit. After one rotation,ring comes in contact with brush and ring comes in contact with. Therefore, brush is all times in contact with the wire moving up in the field, while the other is in contact with the wire moving down
The direction of current in external circuit remain the same. Thus,a unidirectional current is generated.
