A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V.
The secondary winding gives a full load current of 30A at a power factor of 0.8 lagging. Neglecting losses,
Find
(a) The rating of the transformer,
(b) The power supplied to the load,
(c) The primary current
HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial

how does a magnifying glass work to produce a large or smaller image?
Consider a current loop where the circulating current is I. This may be for an example of a coil carrying a current. We will assume that the current loop lies within a single plane
