It works just as well for measuring capacitance. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC. Altium Limited is a software company that provides PC-based electronics design software for engineers.

Simulation Use a small signal AC analysis to generate a plot of vs.

RL, RC, and RLC Circuits ~ reading

You can measure the voltage levels and rise and fall times of the function generator with the oscilloscope to possibly produce a more realistic simulation. Find the Thevenin equivalent voltage and impedance for the output terminals indicated. Give an uncertainty with your result. The primary goal of this assignment is to quickly review what you already know about circuif, inductors, and AC circuits and to extend your new circuit analysis skills to cover sinusoidal signals.


There is also a band pass filter that transmits signals in a frequency band. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit. Otherwise, also sketch your observed oscilloscope trace. Browse over 20, circuit simulations.

Simulation Use a transient analysis. Transitoier RC and Rwgime circuits.

Report an uncertainty in your result. Oliver Heaviside coined the term admittance in December Using the best filter capacitor you can find 3measure the DC level and the magnitude of the ripple across the load. Then, use the function generator to drive your series RL circuit with a sinusoidal wave form. RC circuit – Wikipedia. In electrical engineering, rdgime is a measure of how easily a circuit or device will allow a current to flow.

A full wave rectifier with a voltage regulator. Check your calculations against a Spice simulation. Make note of this. Use the DC direct coupling mode of the oscilloscope or a DVM to measure the the DC level, and use the AC active coupling mode of the oscilloscope to remove the DC component of the signal and zoom in on the ripple.

In order to convert an AC current that spends equal amounts of time flowing in opposite directions into a DC current flowing in only one direction, we need a device that responds differently to applied voltages of different polarities. If not, measure that, too. Also measure the cutoff frequencies of the filter.


Produce plots of and as a function of frequency, and note the predicted resonant frequency. The next step is to use transitoore large capacitor to filter out most of the unwanted variation or ripple in the signal across the load resistor.

The assignment draws from Chapters of your text.

That is, we label the source signal and the potential difference between some other pair of nodesand we think of the network of devices between the input and output terminals to be a filter that transforms into. In your Spice simulation, do not explicitly include the transformer. In time base dn, you can look for the frequency at which the voltage across the resistor is maximal.

Newer Post Older Post Home. Investigate and report on the dependence of the plots and the resonant frequency on the resistanceand explain. A half wave rectifier.

Use this expression to produce a plot of vs. Derive an expression for the resonant frequency of a series RLC circuit in terms of and. Simply treat it as a sinusoidal voltage source.
