Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are go… ...

Measurement of circuit's attenuation factor and generator's internal resistance leads to r c, the capacitor's ESR: Instead of using a sine wave excitation, we can use a square wave.

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor or a run capacitor. Some motors will even use both.

Micropower and low-voltage op amps allow you to build high-performance analog-signal processors that require no batteries or wall transformers. Instead, you can use a capacitor as a power source. The ...

Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found ...
