Real and reactive components of current?

  1. Dec 3, 2007 #1
    Real and reactive components of current??

    1. The problem statement, all variables and given/known data
    Hi there. so im trying to solve this problem but i dont understand some of the terms used,which is obvoiusly causing some trouble. Any explanation of the terms or help would eb much appreciated.
    A coil having a resistance of 20 ohms and an inductance of 0.15 henry is connected in series with a 100*10^-6 Farad capacitor across a 230 V 50 Hz supply.
    Calculate:
    the active and reactive components of the current


    2. Relevant equations
    I'm not too sure because i don't know what active and reactive current is? but i would start by calculating the capacitive and inductive reactance....or?


    3. The attempt at a solution
    I know how to calculate active and reactive power if given I and V and power factor,but not all these quantities are given in the question.
    thanks in advance:confused:
