which of the following rule is used to determine the direction of rotation of dc motor
Which rule is used to determine the direction of rotation of a DC motor?
Answer:
The rule used to determine the direction of rotation of a DC motor is the “Left-Hand Motor Rule”. This rule states that if the index finger of the left hand points in the direction of the magnetic field (flux), and the second finger points in the direction of the current (conventional direction of positive charge flow), then the thumb indicates the direction of motion or rotation of the conductor, in this case, the coil of the DC motor.
By applying the left-hand motor rule, one can easily determine the direction in which the coil will rotate in a DC motor based on the direction of the magnetic field and the current flow through the coil. This rule is fundamental in understanding and predicting the behavior of DC motors.
