Hi, in Multisim 14.2 - Evaluation version, simulating the circuit with an ideal insulating transformer 1p1s, 10:10 turns (1:1 ratio). The transformer primary is excited with a 60Hz AC voltage source, and the secondary is closed through a 10 Ohm resistor.
Q1: Why is my current in secondary changing when I add a voltage offset (DC bias) to the AC source?
Q2: Why current flows in the secondary when the primary side is excited with a DC source only?
Do I need to adjust the transformer model to properly handle the DC presents and how?
