`        At what angular frequency is the voltage amplitude across (a)resistor, (b) inductor, (c) capacitor, in an LCR series circuit at maximum value?`

```										Dear ravi
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
for resister w=1/√LC
for inductor  =√[2C/(2L3 -CL2R2)]
for capacitor=√[(2L-CR2)/2L2 ]
