Reactive Circuits - Please help
Hi there,
I've been having a bit of trouble with a couple of questions on reactive circuits, and am a bit stuck now. The question Im stuck on is below, and I would appreciate any help very much!

(a) Calculate the phasor voltage of the voltage source and the phasor current of the current source in both Cartesian and Polar coordinates. Use peak values when calculating the phasors.
(b) What are the phasor voltage and impedance of the Thevenin equivalent circuit of the power supply? (Use peak values for the voltages and currents in your calculation)
(c) What are the phasor current and impedance of the Norton equivalent circuit of the power supply? (Use peak values for the voltages and currents in your calculation)
(d) At what frequency should the circuit operate for the current flowing through the load and the voltage across it to be in phase?
(e) It is known that for a different load the voltage and current across the load are 240cos(ωot+45°) V and 4cos(ωot+60°) A, respectively. How much power is dissipated in that load?
