This video is about studying resonance in rlc series and parallel circuits. Series and parallel lcr circuits physics lab experiment. Lcr circuit series and parallel psbrahmacharys blog. The frequency corresponding to maximum current is noted and it is the resonant frequency f 0. 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. Parallel resonance in rlc circuit ac circuits basic. Since the current is common to all three components it is used as the horizontal reference when constructing a voltage triangle.
This is fantastic because it gives us a way to analyze rlc circuits using the same methods we learned about for justresistor circuits. The frequencies f 1 and f 2 corresponding to half power points is noted and from it the bandwidth, f 1 f2 is noted. Subscribe to our youtube channel to receive notifications of live classes and. 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. This experiment will be used to examine the sinusoidal frequency response of the series and parallel to see at what. To determine the impedance of an aclcr circuit and verify the impedance relation. Principle in an rlc circuit, energy is exchanged periodically between a capacitor and a coil. When the electric field of the capacitor decreases by discharge over. Current through an inductor lags the applied voltage, so i l appears at 90. You can download the ncert solutions in pdf format as well. Download scholarslearning app from android and ios. Before you connect the circuit to the function generator set the frequency to 60 hz. Current through the resistor is in phase with the voltage dropped across that resistor, so i r also appears at 0. Free shipping and free returns on prime eligible items.
Connection of open circuit test of single phase transformer duration. Video lecture on parallel resonance in rlc circuit of chapter ac circuits. Voltage and current amplitudes in a series rlc circuit. Download ekeeda application and take advantage of this offer. From the values of f 0, f 1 and f 2, the quality factor, q is calculated. Facebook linkedin twitter youtube contact jove recommend jove. Learners examine how voltages and currents vary in a series rlc circuit as the applied frequency changes. The experiment will also demonstrate the oscillatory behavior of an lc circuit. Rc circuits 2 two circuit elements are in series if all of the current flowing through one also flows through the other. This experiment will be used to examine the sinusoidal frequency. Voltage and current amplitudes in a series rlc circuit by terry bartelt. For more e learning videos subscribe to vtu e learning channel and never miss any update. 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.
