Example 30.2 -
The transformer in the above problem has a primary and secondary resistance of 18
Ω
and 5
Ω
,
respectively. The corresponding coils have a reactance of 6 and 2.5
Ω
. The secondary side is loaded with an
impedance of 12.5 k
Ω
. Find the voltage and current on the secondary side in addition to the equivalent impedance
on the primary side.
