An L-R-C circuit has an inductance of 0.410 , a capacitance of 2.75×10?5 , and a resistance of R.
(1) What is the angular frequency of the circuit ?
(2) The capacitor can withstand a peak voltage of 560 volts. If the voltage source operates at the resonance frequency, what maximum voltage amplitude can the source have if the maximum capacitor voltage is not exceeded?
