The figure below shows an AC source, a transformer with a turns ratio of N1/N2 = 2.40, a source resistor RS,and a load resistor RL. A circuit contains an AC source, two resistors, and a transformer composed of two coils. The transformer will bridge two halves of an otherwise disjoint circuit. The left half of the circuit starts on the left at the AC source labeled ΔVS, goes up and to the right to a resistor labeled RS, goes down...
