A lissajous pattern, as shown in figure below, is observed on the screen of a $$CRO$$ when voltages of frequencies $${f_x}$$ and $${f_y}$$ are applied to the $$x$$ and $$y$$ plates respectively. $${f_x}:{f_y}$$ is then equal to

Skew is used in induction motors in order to reduce torque due to

When a transformers winding suffers a short-circuit, the adjoining turns of the same winding experience

Two transformers of identical voltage but of different capacities are operating in parallel. For satisfactory load sharing
