Inductance (L), capacitance (C) and resistance (R) are constained in a box. When 250 V DC is applied to the terminals of the box, a current of 1.0A floes in the circuit. When an AC source of `250V_(rms)` at `2250 rad sec^(-1)` is connected, a current of `1.25 A_(rms)` flows. It is observed that the current rises with frequency and becomes maximum at `4500 rad sec^(-1)`. find the values of L,C and R. draw the circuit diagram.
