How only capacitors can give smooth ac voltage waveform when used...
Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out. Read More »

What value of smoothing capacitor should i use?
The answer sepends on two things: 1. How much current you are going to be drawing from it, and 2. how much ripple is acceptable in the output voltage. Ripple is residual AC voltage that rides on top of the DC voltage. The formula for the ca... Read More »

Generally capacitors are used to smooth DC voltage....I'll give how they do both.... when you convert AC to DC you generally use a rectifier, basically you use diodes that only allow current in one direction...this only gives you half the w...

A capacitor is charging when the amplitude of the voltage wave is rising (thus clipping off the top of the wave, since it is draining the wave to fill itself with charge), and the capacitor discharges when the wave is falling (thus filling ...

Capacitor in Farads = (Period x Current) / Ripple Voltage 0.03F = (0.010s x 6A) / 2V The answer is 30,000 uF for 2 V ripple. A rule of thumb is 4700uF per Amp for 2V ripple. This would deliver a voltage around 15.5V with 2 V ripple, assumin...

A LED cannot be connected to 230 volts without some axillary components. Possibly a switching power supply is causing the flicker. Capacitors smooth dc, so a capacitor possibly won't help with your circuit. I have seen LEDs blink about once...

The capacitor will reduce the variation in the output, but will not regulate it. You can get a 3-volt series regulator, but it won't work with an input under about 5 volts. The capacitor by itself may be enough for your application, dependi...

Look fo a circuit called sample and hold circuit, it is basically a transistor (or op amp) with a cap and resistor at the base. See also my website: http://www.geocities.com/fifaham/NegPulse.htm and peak detector just for an idea: http://ww...

You need a nice fat electrolytic capacitor across the DC outputs of your bridge. Hitting 13.8 is going to be harder. You're going to see 18 x 1.4 Volts DC on the output of your bridge, when you add the capacitor. What current does your rig ...
