SUMMARY

The discussion centers on the correctness of the formula used for calculating the potential difference (P.d) across a coil, capacitor, and resistor in an electrical circuit. The formula provided is f = 1 / (2π√[L.C]), which is a standard equation for resonant frequency in LC circuits. The calculations for P.d across the coil, capacitor, and resistor are presented, with specific values such as 0.32 for the coil and 0.5 x 10^-6 for the capacitor. The inquiry seeks validation of these calculations and the overall approach.

Please see question at . . . . . .http://www.flickr.com/photos/37144556@N07/3475560721/sizes/o/

(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??
