Inductors X1 and X2 are magnetically coupled
- M = 20 [Ohm]
- X1 = 20 [Ohm]
- X2 = 30 [Ohm]
I am not sure how to interpret short circuit. Is the circuit impedance given by the equation:
_Z = R1 + jX1 + j2X4 + _Z1 ?
For a perfect transformer, the primary X1 would appear to be shorted because the secondary X2 is shorted. The impedance would therefore simply be Z1 + R1.
X1 appears in the circuit only to the extent that the transformer is not ideal. There are 4 main contributions to the impedance of X1:
