    Please help me discover the proper formula to use in the following question:

    Objective : Magnitude of Total Current in Amps.

    Parallel RLC circuit contains 4 ohm resistor, a 0.281 H coil and a .25 uF capacitor connected across a 15V, 60HZ source.

    Thank You for you assistance!

    I would find the total impedance of the circuit and then use Ohm's law to find your current and take the magnitude of the result.

    I did the math and came up with approximately 3.75 amps.

    I would like to thank both of you for your response. I really appreciate the two of you taking the time out of your busy day to help me. Roddefig, I also got 3.75 amps as the answer.
    Thank You!
