State Flamings left hand rule and what is the role of split rings in electric motor and how does short circuit happen
Answers
Answer:
Fleming's Left Hand Rule. It is found that whenever a current carrying conductor is placed inside a magnetic field, a force acts on the conductor, in a direction perpendicular to both the directions of the current and the magnetic field.
Explanation:
Split ring is used for reversing the direction of current in the coil. ... Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction
A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.
