Complex Power and Impedance

An electrical load operates at 240 volts rms. The load absorbs an average power of 8kW at a lagging power factor of 0.8. a) Calculate the complex power of the load. b) Calculate the impedance of the load. Please see attachment for multiple choice options.

Transformer and Load

In the following circuit find Ix and Iy. HINT: First find Ix by replacing the transformer and load at point x, x with the transformed load impedance. Please see attached for diagram and multiple choice options.

Current Flow

Consider the following circuit. Approximately how much current will flow through the 1K OHM resistor in parallel with the current source? Please see attached for diagram and multiple choice options.
