I really liked this video. Its the first one that actually shows a practical use for an electronic component. Ive been dabbling in electronics for years and ive read several books in it. The trouble i have is everything explain things like this: here is a capacitor, it stores electricity, here's a circuit that uses a capacitor, next topic. That doesn't really help me to understand what its purpose is and what its doing in that circuit or how its value was decided. Im looking for a way to learn electronics in a way that i can look at a circuit and see why ever component is there and what its doing in the circuit. Can you suggest some kind of linear path to take to start learning electronics more in depth?

Congratulations for the quality of your videos. I got a few questions for you... On the differences between electrolytic and ceramic capacitors. I know one is polarized while the other is not. What makes an electrolytic capacitor polarized? Nothing in the capacitor theory would point to this...Would using an electrolytic capacitor equal to using a ceramic capacitor plus a diode? How come when larger capacitors are needed almost always electrolytic capacitors are used?

Great job on these videos... I have a ba in electronics and it is such a vast field... I like tonusebur videos as a fresher... to get straight to the point of the usage of the components. ..I no how to calculate everything. .. but what isnt really taught in books are the utilities of the components. .. like de coupling... I didnt really understand it and now i do.. thanks a lot now go over inductors... its good thatbu don't go to far into deriving the equations because it just takes to long.

I want to talk to you about a couple things. 1st, thanks for taking the time to go over basics. I started doing some pretty intense "DIY" pro audio work i.e. building mics, preamps, analogue gear, etc. and I honestly don't understand why it works & how I could modify gear I already have. I too am working on a video log and blog that will help others learn about DIY audio and recording. i was wondering if you could go over Schoep's Circuit? I'd like to have you on the blog to answer Q's? Cool?

Great vid thanks. A cool suggestion for a topic would be solar power point tracking and low power current sensing with uC like 328p. Also I wonder if maybe the uC could be used as an ideal diode controller with two p mosfets with gates tied. If so that would be great. I love making the most of power and building circuits carefully to be lean.

I am in the infancy stage of Electronics 101. To this point, I need a major clarification on battery voltage. You see many of these tiny, rectangular, 9V batteries being used on breadboards. A riding lawn mower typically has a 12V battery which is considerably larger than the tiny, rectangular 9V battery, yet the voltage comparison is 9V to 12V. Adding to my confusion is a 12V car battery which has the same 12V rating as the riding lawn mower battery, yet the car battery is quite a bit larger and heavier. What am I missing that differentiates between these voltage readings: 9V rectangular battery versus 12V mower battery versus 12V car battery. Thanks!!!

I would like to compliment you on your electronic 101 tutorials, very good and thorough! the explanation of the high and low pass filters with the circuit simulator was excellent, Afrotechmods would've been proud of you.

Ian Turner usually "signals" are read as voltages. For example, some circuits might interpret anything above 5V to be a "1" while less than 5V is a "0". Thus, you can do logic operations in binary :)

I understand one formula for capacitors, which make a lot of intuitive sense, and seems deceptively simple: that the derivative (how fast it is changing) of the voltage across a capacitor is proportional to the current, for a given capacitance. HOWEVER, what I do not understand is how to convert this relationship, substitute ohms law into it, and solve it. Currently, after some algebra, I was able to figure this relationship out: C*dV(1)/dT = (V(2) - V(1) ) / R. I got that from realizing that V=IR, and that dV/dT*C = I. Just substituted the 2 together. I do not know how to simplify that further though, to end up with that weird inverse exponential curve that is the charging curve.

my shallow well pump will not start , I swapped the capacitor with a different pump and it works , the old capacity off the pump was 124 - 148 UF , watching videos on KZitem I came to the understanding that I could install something which is 5% less or 10% more from the original , the question is? if I install a larger capacity will that extend the it's life expectancy ? Old capacitive part number 61B1D 120124NNAO , 680171-001 , it has the manufacturing date of 16/07/2010 , My swimming pool pump had the same capacity for over 15 years no problems , I guess they don't make them like they used to. your input is appreciated thank you have a nice day .

Hi.. Hoping you can point me in the correct direcrion. I am trying to sup up a sander with a washing machine motor. I was told i need a start cap or (according to my research a run cap) i think i would perfer a run cap to help with performance. I already have the, "i think single stage motor" jerry rigged to the sander. When i switch it on it hums until i physically assist it. Was wondering if you inform me on what run cap i could purchase for a 5 amp 115v ge washing machine motor.... Thanks

Note: I have no idea what I'm talking about, but trying to understand this. When you first state that there is a buildup of electrons on one plate, and they want to get to the other plate with no electrons because "They don't like each other"- are you referring to the entropy, and the thermodynamic equilibrium? That's kind of how I understand it, but let me know if I'm wrong.
@dp0813
6 жыл бұрын
GoFuckYourselfKZitem no, he's just referring to the "same polarities repel" rule. Electrons have negative charge so they want to "escape" from the other electrons & move to the less negative (or more positive, relatively) plate. The dielectric material between the plates (& the gap) prevents that from happening under ideal conditions.

I'm not positive so dont quote me, but i don't think this discharge will do anything for you as far as the 'explosion' of torque and force that you want out of your motors. I pretty sure though that it will help it get to and maintain top speed once it is off without any jumps in power running through the motors or motor and in turn increasing the life and efficiency of the motors. Please reply if you learn or have learned otherwise, saying as i am a few months behind your post.

If a capacitor has a rating of 10,000 mfd and a voltage rating of 60volts I know it's maximum operating voltage is 60 volts, but what I want to know is, if the circuit only applies 30 volts to the capacitor does it only charge to 5,000mfd?
@humanHardDrive

No. The voltage has to do with when the dielectric of the capacitor will fail. It's still a 5,000 mfd capacitor even if you only partially charge it.
