Potentiometer Basics - How they Work | Basic Electronics

Potentiometers, trimmers, and rheostats are used in a lot of electronics and they're not only useful but interesting! We take a potentiometer apart, discuss the differences between analog and digital potentiometers, as well as linear and logarithmic tapers (how they change). Check out the video to see how they work, where they work, and why you'd want to use the different types.

Great explanation. It made me realize potentiometers are not as complex as I thought.

Exact informational video I was looking for. Recently got into electronics and building a lot of projects. One project is a benchtop power supply using an ATX. I'll be adding a cheap Chinese Up/Down converter, a Volt/Current Display and a pot to vary the voltage of a 12V connector. When ordering pots, now I understand what the "A" and "B" are referring to in the descriptions. Please consider this project for a video. Cheers

very well explained, (for a novice like me ) thankyou

[qaz]

Great channel sir and content-full video Thanks a lot

[naderhumood]

Would you mind making a vedio about, wiring potentiometer...many thanks. Sir.

Is the logarithm mode the voltage driver mode?

[trishbroncheau]

THANK YOU for posting this video. Your presentation was informative on a top tier level. Excellent clarity as well.
Again, thanx from your latest subscriber!!! 》☆《

Is it possible to control 3 LEDS with there own resistors in parallel simultaneously with a potentiometer. And if so how

[petertowers]

My question im s what type of potentiometer do I use to control the speed on my son's electric 24v gocart?

[gavinw]

There's lots you didn't explain, like what does the center pin do. I don't see what it can possibly do. The outer pins conduct current. But it seems to me, that's all that's needed. The center pin isn't needed. And how do we use a volt-meter with these. When I tested the dial, I didn't observe any change in resistance (connecting the volt-meter to the outer pins).

Can I solder a normal 100 kOhm resistor to a 100 kOhm multiturn potentiometer in order to get to 200 kOhm? Can't find a 200 kOhm multiturn potentiometer!

Just preparing for an exam, thanks for helping me out.
And One more thing, your hands could use some stability.. no offence but its really distracting( the shaky hands)

i dont know if its me but, this video became out of focus
