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.......

 

To start with determine the currents: http://www.allaboutcircuits.com/vol_2/chpt_5/3.html

You should then be able to do the phasor diagram. Try that then we can look at the power aspects of the question later.
