Answer / manoj

it is a voltage drop on full load of atransformer mainly
because of winding resistance and leakage reactance

Answer / mac ball

In electrical engineering, impedance measures how easily a
circuit conducts current when a voltage runs through it.
Measured in ohms, impedance is a way of telling you how
much of the voltage introduced at one end will really make
it to the other end. Impedance depends on other qualities
of electricity, such as resistance, reactance, inductance,
and capacitance.
