Series and parallel lcr circuits physics lab experiment. The experiment will also demonstrate the oscillatory behavior of an lc circuit. Then, using the voltmeter set the generators output to 5 volts rms. The experiment will demonstrate the transient behaviors of rc and rl circuits using a light bulb resistor. The frequencies f 1 and f 2 corresponding to half power points is noted and from it the bandwidth, f 1 f2 is noted. Principle in an rlc circuit, energy is exchanged periodically between a capacitor and a coil. For more e learning videos subscribe to vtu e learning channel and never miss any update. This experiment will be used to examine the sinusoidal frequency.
Current through the resistor is in phase with the voltage dropped across that resistor, so i r also appears at 0. Using the protoboard and wire leads connect the resistor, capacitor, and inductor along with the output of the function generator to construct the circuit shown in figure 1. From the values of f 0, f 1 and f 2, the quality factor, q is calculated. The frequency corresponding to maximum current is noted and it is the resonant frequency f 0.
This video is about studying resonance in rlc series and parallel circuits. When the electric field of the capacitor decreases by discharge over. Voltage and current amplitudes in a series rlc circuit by terry bartelt. To determine the impedance of an aclcr circuit and verify the impedance relation. This is fantastic because it gives us a way to analyze rlc circuits using the same methods we learned about for justresistor circuits. Facebook linkedin twitter youtube contact jove recommend jove. Before you connect the circuit to the function generator set the frequency to 60 hz. Learners examine how voltages and currents vary in a series rlc circuit as the applied frequency changes. Download scholarslearning app from android and ios. Video lecture on parallel resonance in rlc circuit of chapter ac circuits. This example shows how to analyze the time and frequency responses of common rlc circuits as a function of their physical parameters using control system. For more information about professor shankars book based on the lectures from this course, fundamentals of physics.
In a series rlc circuit containing a resistor, an inductor and a capacitor the source voltage v s is the phasor sum made up of three components, v r, v l and v c with the current common to all three. Rc circuits 2 two circuit elements are in series if all of the current flowing through one also flows through the other. Lcr circuit series and parallel psbrahmacharys blog.
