Question

Do the following:

  • Solve for the voltage across the appliance and the current through it by referring the appliance to the transformer primary. (Assign the convenience outlet voltage as the reference phasor i.e. at 0o)
  • Draw the circuit that would solve for VL and IL. Compute all referred values and label all components.
  • Solve for VL and IL
Your aunt living in the USA sent an appliance that has impedance equal to 10 + j3 at 60 Hz. She instructed you to purchase a 220 V to 110 V transformer to step down the voltage since the appliance is rated 110 V. The cord that you used to connect the 220 V side of the transformer to the convenience outlet has a total impedance of 1 + j0.5 Q. You measured the voltage at the outlet and the value is 220 Vrms. The equivalent circuit is shown below: 1Ω ī + 10 + j3 V Ω 220 V 110 V j0.5 Q m 220 V rms
