How to Calcolate Capacitive Reactance

Capacitive Reactance Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing through it. Capacitors, unlike resistors, are reactive devices. This means that they offer different resistances to...

What is a Bypass Capacitor???

What is a Bypass Capacitor? A bypass capacitor is a capacitor that shorts AC signals to ground, so that any AC noise that may be present on a DC signal is removed, producing a much cleaner and pure DC signal. A bypass capacitor essentially bypasses AC noise that may...

What is a Smoothing Capacitor ???

What is a Smoothing Capacitor? A Smoothing capacitor is a capacitor that acts to smooth or even out fluctations in a signal. The most common and used application for smoothing capacitors is after a power supply voltage or a rectifier.Power supply voltage can sometimes...

What is a Coupling Capacitor ???

What is a Coupling Capacitor? Use of Coupling CapacitorsA coupling capacitor is a capacitor which is used to couple or link together only the AC signal from one circuit element to another. The capacitor blocks the DC signal from entering the second element and, thus,...

How To Test a Capacitor ???

How To Test a Capacitor In this article, we will go over different tests that we can use to tell whether a capacitor is good or not, all by utilizing the functions of a digital multimeter. There are many checks we can do to see if a capacitor is functioning the way...

What are Capacitors Used For ???

What are Capacitors Used For? Capacitors, either standalone or used with other electronic components such as resistors and inductors, have a wide variety of uses in circuits. What capacitors are used for are shown below: 1) RC Timing Circuit A capacitor, when combined...

How to Create a Non-Polar Capacitor From a Polar Type ???

Instructions..... 1 Examine the capacitors. The body has a polarity mark on one side, such as a minus sign. One lead may be shorter than the other; if you see this, the shorter lead is the negative side. 2 Solder the negative leads of the two capacitors together,...

Just Do a Timer Circuit with 4060B

Timer Circuits With 4060B There are many applications for which a timer is very useful to turn a device on or off automatically after a preset interval - for example, switching off an irrigation system after 30 minutes of use, turning off a battery...

What is e ???...Must read it.... :-) ...

e (Euler's Number) The number e is a famous irrational number, and is one of the most important numbers in mathematics. The first few digits are: 2.7182818284590452353602874713527 (and more ...) It is often called Euler's number after...

What is log ???...A crispy Note.....

Introduction to Logarithms The Word "Logarithm" is a word made up by Scottish mathematician John Napier (1550-1617), from the Greek word logos meaning "proportion, ratio or word" and arithmos meaning "number", ... which together makes "ratio-number"...
