Capacitor Circuits: Capacitor in Series, Parallel & AC Circuits
Hence, the charge stored by the capacitors is also the same (i.e. Q T = Q 1 = Q 2 = Q 3), because charge stored by a plate of any capacitor comes from the plate of adjacent capacitor in the circuit. By applying Kirchhoff''s …
What is Capacitor Start Induction Motor? Working Principle, …
Ans: The direction of rotation of capacitor start motor can be reversed by interchanging the connections of starting winding without disturbing the capacitor connections. The direction of motor can be reversed only before the starting operation of the motor i.e., when the motor is at rest and the centrifugal switch is in closed position.
