Need help with practice problem

A resistor (R), a capacitor (0:0.25 pF), and an inductor (L=2.5 H) are connected in series across an AC source for which Vp=140 V. When the source operates at resonance angular frequency, the peak value of the current in the circuit is 0.2 A. a) What is the resonance frequency of the circuit b) What is the rms value of the maximum current can be delivered from this circuit When the source is Operating at 240-Hz, calculate: c) The peak value of the current in the circuit Up.) d} The rms value of the voltage across the inductor
