An RLC circuit includes a `1.6` H inductor and a `250 muF` capacitor rated at 400 V. The circuit is connected across a sine - wave generator whose peak voltage is 32 V. What minimum resistace must the circuit have to ensure that the capacitor voltage does not exceed its rated value when the generator is at the resonant frequency? Fill 10 R in OMR sheet.

An A.C circuit contains a resistor 'R' an inductor 'L' and a capacitor 'C' connected in series. When it is connected to an A.C generator of fixed output voltage and varialbe frequency, the current in the circuit is found to be leading the applied voltage (pi)/(4) read, when the frequency is f_(1) . when the frequency of the generator increased to f_(2) the current is found to be lagging behind the applied voltage by (pi)/(4) rad. The resonant frequency of the circuit is
