Question
**Educational Content: Calculating Equivalent Impedance** **Problem Statement:** For the circuit shown, what is the equivalent impedance between nodes \( a \) and \( b \)? **Circuit Description:** The circuit consists of two pairs of coupled inductors connected with impedances. Each pair of inductors is represented with turns ratios: - The top pair is marked as \( 20:40 \). - The bottom pair is marked as \( 40:20 \). On the right side of each pair of inductors are complex impedances: - Top impedance: \( 16 + j20 \, \Omega \) - Bottom impedance: \( 6 + j10 \, \Omega \) **Options for Equivalent Impedance:** 1. \( 65.5 + j82.5 \, \Omega \) 2. \( 10 + j15 \, \Omega \) 3. \( 28 + j45 \, \Omega \) 4. \( 22 + j30 \, \Omega \) **Explanation:** To find the equivalent impedance between nodes \( a \) and \( b \), consider the transformation properties of the inductors based on the given turns ratios. This involves calculating the reflected impedance of each inductor pair. Students are encouraged to perform the necessary calculations or simulations to determine the correct equivalent impedance from the given options. **Note:** Complex impedance is composed of a real part (resistance) and an imaginary part (reactance), denoted by \( j \). **End of Educational Content.**
