Question
**Circuit Analysis Problem** For the circuit shown, what is the primary current, \( I_1 \)? **Diagram Explanation:** - The circuit includes an AC voltage source with a magnitude of \( 20 \angle 30^\circ \text{V} \). - On the left of the circuit, the source is connected to a series impedance of \( 3 - j5 \, \Omega \). - The primary side of a transformer is present, represented with a turn ratio of \( 150:300 \). - The secondary side of the transformer connects to a load impedance of \( 12 + j2 \, \Omega \). **Options for \( I_1 \):** - \( 2.67 \angle 66.9^\circ \, \text{A} \) - \( 2.25 \angle 30.0^\circ \, \text{A} \) - \( 0.39 \angle 26.6^\circ \, \text{A} \) - \( 1.31 \angle 41.3^\circ \, \text{A} \) To solve for \( I_1 \), use principles of AC circuit analysis, considering impedance transformations across the transformer.
