Capacitors
What is a capacitor used for?
I understand so far that a capacitor is used mainly for leveling out voltage spikes and ripples is a voltage supply. Like for a voltage regulator LM7805.
** At any time, please correct me if I'm wrong, because I'm not a professor, nor an electronics expert, instead, I'm a 24/7 student. I'm always trying to learn something about electronics, even if it's very simple to some people.
I also hear recently that a capacitor is used for motors. In order for the motor to start up, it needs a capacitor.
So is that basically what Julian is talking about, because when the wireless transceiver starts up, it draws a lot of power, and the capacitor is used to do something about the current?
2m 29s Into the video. The "link" is supposed to start the video at that time, but it doesn't seem to work.
Why do you use a 0.1uF capacitor on one circuit, and use a 20uF capacitor on another.
According to Google, farads is the SI unit of electrical capacitance, equal to the capacitance of a capacitor in which one coulomb of charge causes a potential difference of one volt.
I'm pretty good with buying and using n-Channel MOSFETs, and I have no problem finding the resistor value for an LED. But I've been trying, slowly, to get a better understanding of different electronic components.
If I needed a reply for this, a specific reply, I'd request it was a reply to what capacitors are used for. Maybe in the form of a neat list.. something similar to the following example.
Also, what is the difference between a 1uF and a 1F capacitor.
Farads being a unit of
1. Voltage spikes, and ripples in voltage.
A little more explanation of #1.
2. Current.. motors, IDK.
A little more explanation of #2.
3. Something else.
A little more explanation of #3.
I'm not young, and I'm not in school. I'm in my early 30's, and have a slight interest in electronics. I simply would love to learn and have a better understanding of how electronic components are used, and what they are used for.
I could watch videos and search the entire internet for hours, or even days, and not learn, get, or understand what I'm trying to learn. When I could just come here and ask a specific question, and get a straight answer, and have a very clear understanding of what they're used for, and why. By people that have experience and knowledge under their belt about stuff that people like myself, have no clue about.
