Question

How do I find:

a) The effective impedence seen by the source at the primary side of the ideal transformer, assuming the V0 port is unloaded

b) The output voltage V0

The image represents an AC circuit schematic comprising the following components:

1. **Voltage Source:**
   - A sinusoidal AC voltage source is depicted with a value of 120V.

2. **Components in the Primary Side:**
   - A resistor with a resistance of 20Ω.
   - An inductor represented by an impedance of \(j40Ω\).

3. **Transformer:**
   - A transformer with a turns ratio of 2:8 is shown, separating the primary and secondary sides of the circuit.
    
4. **Components in the Secondary Side:**
   - A resistor with a resistance of 60Ω.
   - An inductor represented by an impedance of \(j100Ω\).
   - A capacitor with an impedance of \(-j20Ω\) connected in parallel.

5. **Output Voltage:**
   - The output voltage \( \tilde{V}_o \) is denoted across the capacitor.

This circuit illustrates the analysis of AC circuits with transformers, incorporating reactive components such as inductors and capacitors. The impedances are expressed in complex notation, indicating the phase difference introduced by the inductive and capacitive elements.
