When the primary of a transformer is connected to a 120 V AC mains, the current in the primary is 18.5 mA. Find the voltage across the secondary when it delivers 1.5 mA current through it, assuming the transformer to be an ideal one. State any one type of energy loss in a transformer.
For an ideal transformer,
ip x Vs = is x Vs
Here,
ip = 18.5 mA
Vp =120 V
tS = 1.5 mA
and VS = ?
Using values in equation,
18.5 x 120 = 1.5 x Vs
Hysteresis loss is an energy loss in a transformer.
