Coupled Electrical OscillatorsPurpose:To demonstrate damping of two coupled oscillatory systems.Procedure:Set up the circuit as shown below. Set signal generator to square wave and run through frequency ranges until resonance is found. (Resonance is the point at which the amplitude of the output is maximum.) Note the damping effect.Hints:Use 1 .1 mf capacitor, 2 .47 mf capacitors, 1 10k 1/4W resistor and 4.25 MH air core copper coil inductorEquipment:
