Cant seem to get my head around this question so any advice would be greatA circuit with an inductor(with both resistance and inductance) Vrl (200+j300)V connected in series to a capacitor c150 micraF across a power supply with a 50Hz supply voltage. The supply current is 25lt;0 degreesCalculatea) impedance of the inductor expressed in complex formb) the values of R and L of the inductorc) the value of the supply voltage, expressed in polar formd) the phase angle of the circuite) the apparent and active powers of the circuitf) draw a scaled argand diagram showing the supply current and all voltages
you better to see the transmission lines and waveguide book
