Explanation / Answer

current in LC R circuit

i = V/[R2 + (1/wC -wL)2]1/2

voltage across resistor = iR = VR /[R2 + (1/wC -wL)2]1/2

voltage across inductor = iwL = VwL /[R2 + (1/wC -wL)2]1/2

voltage across capacitor = i/wc = V /wC[R2 + (1/wC -wL)2]1/2

For maximum value differentiate each w.r.t w and put equal to zero

A)for resistor w=1/LC

B) for inductor =[2C/(2L3 -CL2R2)]

C) for capacitor=[(2L-CR2)/2L2 ]
