Homework Help: Am I using the correct formula?

  1. Apr 26, 2009 #1
    Please see question at . . . . . .http://www.flickr.com/photos/37144556@N07/3475560721/sizes/o/ [Broken]

    (B) f = 1 / (2.pi. square root of [ L.C ] )

    (C)

    (1)P.d across coil = 2.pi.f. (0.32)

    (2) P.d across capacitor = 2.pi.fr.(0.5 x 10^-6)

    (3) P.d across resistor = 30v - (1) - (2)

    (ii) Current = 30/60

    Is this correct??
