77 II. Set-up and Procedure: 1. The series and parallel LCR circuits are to be connected as shown in fig 1 & fig 3. 2. Set the inductance of the variable inductance value and the capacitances the variable capacitor to low values ( L ~ 0.01H , C ~ 0.1 F ) so that the resonant frequency C L 2 1 O ± = is of order of a few kHz . 3. Choose the scale of the AC mill voltmeter so that the expected resonance occurs at approximately the middle of the scale. 4. Vary the frequency of the oscillator and record the voltage across the resistor. 5. Repeat (for both series and parallel LCR circuits) fir three values of the resistor (say R = 100 ,200 & 300 ± ). III. Exercises and Viva Questions: 1. Write down the Newton’ s law for a forced damped harmonic oscillator and map the electrical quantities appearing in eq (2) with corresponding mechanical quantities. 2. Verify that the solution, eq (3) satisfies the differential equation (2). 3. Distinguish between resistive impedance and reactive impedance. What is the
