    Hello, I'm in my second year HNC and is my only outstanding assignment which i need help with. The following questions with the working out are required.

    The circuit is an RLC parallel and the following are the known given value's;
    Votage suply = 30vac at 50Hz
    capacitor = 150uF
    Resistor = 18 ohms
    inductor = 100mH


    Question 1a). Determine all currents
    b) use the currents in (1a) to draw a scaled phasor diagram
    c) Determine the following for the circuit
    Active power
    Apparent power
    Reactive power

    d) Use the results in (c) to draw a power triangle
    e) determine the power factor


    If any one could please help me with completing this assignmen then it would be much appreciated.
    Thanks in advance people.......
