A transformer is a device that transfers electrical energy
from one circuit to another through inductively coupled
electrical conductors. A changing current in the first
circuit (the primary) creates a changing magnetic field.
This changing magnetic field induces a changing voltage in
the second circuit (the secondary). This effect is called
mutual induction.
The e.m.f. required to drive electrons across inductive
and capacitive loads vary depending upon the powerfactor
at which the load is designed. The power factor in case of
resistive load is 1 and always remains so. Also, for change
in e.m.f., L and C loads receive varying responses. In
case of resistive loads, the response is steadier for a
longer duration compared to capacitive or inductive loads.
