In a series LCR circuit the phasors corresponding to voltage across resistance, capacitor and inductor at an instant are as shown in the Figure and have amplitudes of` V_(RO) = 4 "volt", V_(CO) = 3 "volt", and V_(LO) = 6 "volt"` (a) Is the source frequency larger than or lesser than the resonance frequency? Does the current (I) lead or lag the source voltage? (b) Find the voltage amplitude of the source. (c) If VR phasor makes `theta=53^(@)` at time t = 0, write the source voltage as function of time. Take angular frequency of the source to be ` omega[sin53^(@)=(4)/(5)]`
