Resistors, capacitors and inductors are the most basic components in electric circuits. It must be ensured that they work properly and accurately. Therefore, they need to be tested thoroughly during circuit design. This is usually done using LCR meters, which have become indispensable in the lab and in production.

If the output capacitor has large ESR (typical for Aluminum Electrolytic), the ripple shape is more triangular (ESR dominated). If there is some ESL (see the OSCON type waveform) you will notice some voltage steps at the peak and valleys of the ripple waveform. If you use ceramic capacitor, the voltage ripple will be sinusoidal since the ESR

In this article, we discussed in detail about the three most basic electric circuit elements namely resistor, inductor and capacitor. From the above discussion, it is clear that a resistor dissipates the electrical energy in the form of heat which cannot be recovered. On the other hand, inductors and capacitors store the electrical energy in the form of magnetic field

An RLC circuit consists of three key components: resistor, inductor, and capacitor, all connected to a voltage supply. These components are passive components, meaning they absorb energy, and linear, indicating a direct relationship between voltage and current. RLC circuits can be connected in several ways, with series and parallel connections
The impedance of a capacitor decreases with the frequency of the AC signal and the capacitance value. Q factor: The Q factor of an inductor is a measure of the quality of the inductor, which is a measure of how well the inductor stores energy in its magnetic field. It is defined as the ratio of the inductive reactance to the resistance of the

To measure the capacitor we’ll simply which will charge (periodically with a square wave) it through a resistor and measure how much time it takes the capacitor to charge to 63% we can then calculate its value according to the RC time constant formula which is t = RC. We’ll rearrange it to C = t/R to get out the capacitance.
The capacitor voltage is measured with two leads across the capacitor and is connected to the AI 1+ and AI 1- screw terminals. The resistor voltage is measured with two leads across the resistor and is connected to the AI 0+ and AI 0- screw terminals. From your NI ELVISmx Instrument Launcher strip, select [FGEN].

Equipment used: For this application, most professional-grade oscilloscopes and function generators will give acceptable results since the test frequencies are 100 kHz and lower.
To measure the inductor we’ll need to make an LC tank circuit. The rising edge of the square wave signal will cause it to ring. Then we can measure the frequency of the ringing which we can input into the LC tank formula L = 1/sqrt ( (2*Pi*f))*C and calculate the inductance. This is what it looks like on a piece of the prototype board.
