Q2: A 100-ohm resistor is connected to the secondary of an ideal transformer with a turns ratio of 1:4 (primary to secondary). A 10-V rms, 1-kHz voltage source is connected to the primary. Calculate the primary current and the voltage across the 100 - ohm resistor.

A 25 kVA, 2 kV(rms)/100 V(rms) single phase transformer is connected between a 120 V(rms) utility supply and a resistive load. The load current was measured to be 20 A(rms). i. Determine the active power of the load. ii. Determine the primary RMS current. iii. Determine the equivalent resistance of the transformer as seen by the utility supply.
