What does a capacitor do?

I link it throughout the resistor as well as the led.

In this video clip, I’m attaching a circuit with a resistor and also an led. To reveal you precisely what a capacitor does.

I reconnect the power, and also the LED lights up once more.

The LED lights up when I link the and also as well as the minus from the battery.

Absolutely nothing wonderful right here.

Next off, I’m attaching a capacitor.

As well as in the precise minute when I detach the power, the LED switches off.

Take an appearance at what takes place when I separate the power:

The LED remains on!

It billed up when I linked the power.

Or to make filters.

Since the capacitor is kinda like a small battery, this is.

As well as after a couple of secs, you can see it fading out.

When I separated the power, it began utilizing its saved power to maintain the LED on.

This is extremely helpful to produce instance a dead time in a circuit.

If you have no suggestion what a filter is, below’s a straightforward one:

Many thanks for seeing!

With the capacitor, you’ll filter out the OFF durations as well as obtain an LED that is constantly on.

Envision an awful battery that somehow maintains transforming the voltage on and also off every secondly.

Without the capacitor, the LED would certainly be blinking.
