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 ]
