    Parallel circuit with resonant branch

    Right got that, so a parallel circuit, the resonant branch impedance is 5 Ohm at angle 0, the lone capacitor branch is 35.2 angle -90 deg. Thats product/sum = 4.9 at angle -8.1 or 4.9+j0.7. With a source of 1Vrms, how do you work out the current drawn, what is with the "rms" part...

    Parallel circuit with resonant branch

    OK sorry, I got the figures wrong. The RLC branch is made of a 5 Ohm resistor, a 30nF capacitor and a 0.2H inductor. My bad, Can anyone shed any more light on this now...? Thanks.

    Parallel circuit with resonant branch

    Am I wrong in thinking the formula for resonance was 1 over 2 x pi x sqrt(LC)

    Parallel circuit with resonant branch

    Here's a question my mate asked me to help out with, but I'm a bit stuck, any help would be good. Apologies for not being able to show the circuit (don't know how) so I'll explain it. A parallel circuit has a supply of 1 Vrms and has 2 branches. The first branch has a single capacitor of 2.2...
