The total impedance Z, of a circuit containung an inductor with inductance L and resistance R in series is given by Z  R  j2fL where f  frequency . If Z  (50  j200)ohm and f = 50Hz. Find R and L

A 15µF capacitor and a 470 ohm resistor are connected in series with a function generator. The supply voltage is 50V RMS 40Hz. Find the reactive power for this circuit.

Consider the sinusoidal voltage and current for an inductor. If you are given the phase angle of the voltage, the phase angle of the current will be:a) The same as the voltage phase angleb) 90°more than the voltage phase anglec) 90° less than the voltage phase angled) Dependent on the inductance
