Am i using correct formula?

Please see question at . . . . . .http://www.flickr.com/photos/3714455...60721/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??

Thanks
