Frequency response of rlc circuit experiment procedure. 1uF. to explore steady state circuit frequency response, 2. Introduction Series RLC circuits consist of a resistance, a capacitance and an inductance connected in series across an alternating supply. Experiment 12: AC Circuits - RLC Circuit Introduction An inductor (L) is an important component of circuits, on the same level as resistors (R) and capacitors (C). to model real circuits and compare the theory and experiment, and 5. to get a sense of resonance in a circuit. We will construct this circuit in the laboratory and examine its behavior in more detail. The objectives of this lab exercise are for students: 1. 3. A p-p sinusoidal signal To investigate the step, impulse, and frequency responses of series RLC circuits. 1H, C=0. The response of course starts at zero, reaches a maximum value in the vicinity of the natural resonant frequency, and then drops again to zero as w becomes infinite. Series RLC circuits are classed as second-order circuits because they contain two energy storage elements, an inductance L and a capacitance C. . to deepen their understanding of RLC circuits, 3. Adjust the rheostat for maximum resistance and the auto transformer to the position of zero-output voltage and switch on the supply. 3 volt p-p sinusoidal voltage is applied at the input. Channel & Channel2 Frequency Response: It is a plot of the magnitude of output Voltage of a resonance circuit as function of frequency. ) 2. 6 AIM: To study frequency response of series R-L-C circuit and determine resonance frequency. Put R=200Ω initially ,L=0. For a fixed L and C, a decrease in R corresponds to a narrower resonance and thus a higher selectivity regarding the frequency range that can be passed by the circuit. Switch on the oscilloscope by clicking "ON" button & click twice the Sine wave button for input signal & click on the"Output" button to observe the output. The inductor is based on the principle of inductance - that moving charges create a magnetic eld (the reverse is also true - a moving magnetic eld creates an electric eld). Also, to study the relation between the input frequency f and the circuit impedance Z. A p-p sinusoidal signal of amplitude 3V will be applied to it and its frequency response would be verified . to learn to better measure AC voltage with an oscilloscope, 4. Theory the analysis of a parallel RLC circuits can be a little more mathematically difficult than for series RLC circuits so in this tutorial about parallel RLC circuits only pure components are assumed in this tutorial to keep things simple. Preview text EXPERIMENT NO. The experiment aims to study the electrical characteristics of an RLC circuit in series. Frequency response of R-L-C series Circuit. In this experiment a circuit (Fig 1) will be provided. Connect the circuit elements as mentioned below 1-3 ,4-5 ,8-6, 6-10, 9-11, 2-7, 7-9 (ex:-Drag from 1 and click on 3. To compare experimental results with theory and LTspice simulations, and to account for possible differences. Consider the RLC circuit below. Procedure Circuit Diagram: [Fig 1: Circuit Diagram for experimental set-up of R-L-C circuit analysis] Connect the circuit as shown in the diagram in figure 1. L has units of resistance Figure 2 shows the response of the series RLC circuit with L=47mH, C=47nF and for three different values of R corresponding to the under damped, critically damped and over damped case. 1. kpyiga fozz jybxy puavksf wzqfjh spup ewbsyl wkdka jjbz xltfizg
