1) three types of inductors in electrical circuits?
2) TWO application of the capacitor in a simple transistor amplifier circuit?

I want to make sure that this 60/40 clear flux solder from radioshack (.063") won’t damage my tv. I need to replace a capacitor on my 37" lcd magnavox. Would rosin core be better?

Ok so a friend and I are having a disagreement.. He says a "switcher" opens and closes circuits, while I think its a transistor.

heres a copy of the question. A(n)____, Which is contained on an integrated circuit, can act as an electronic switch that opens or closes the circuit for electrical charges..

Also might be a capacitor..

Hi, i’m having a little trouble. A schematic diagram of a 3-band equalizer is on this link: http://freecircuitdiagram.com/2008/11/25/3-band-graphic-equalizer-circuit/

Here’s a story. I went to a local electronic shop to buy the parts needed for that 3-band equalizer. When I asked the vendor for the capacitors, he asked me, "how much is the voltage? what kind of capacitor do you need?" and i just said, "i don’t know". The supply needed is 12V DC and the values of the capacitors are:

0.1uF
47nF
4.7nF
0.47nF
22nF
1nF
33uF

I’m sorry but I’m such a noob at this, but I’d really really appreciate it if anyone can help or tell me if there’s some sort of formula for this.

Thank You very much

What is the full name of an Element starting with Q?
On a circuit board there are labels. For example for resistors it is "R", for diode "D", for capacitor "C" what is "Q" for?

I am requesting support from someone who knows electronic power circuits. I have an AC adapter, input 120VAC, two outputs: 32VDC & 16VDC. I connect a voltmeter to either output and when I plug it in, output is instantly correct but then slowly reduces to zero asymptotically. It will not deliver any output again until is it unplugged and plugged it again. It then jumps to the correct output, then repeats the slow reduction to zero. I know enough to suspect that the slow fade-out is a DC capacitor discharging but beyond that I don’t know what components to check or how (other than one-way continuity of diodes, resistance of resistors, etc. I have completely eliminated the possibility that it’s a faulty connection or power cord.

Has anyone ever thought, experimentally, about trying to use compound spirals, maybe even with different materials, or semiconductor styles, in different parts, and other compound shapes, and materials for electronic components?
Example: On the surface of circuit board, etch a twin spiral, with two conductors running parallel to each other as they spiral toward the center, with a solder hole at each ones’ ends so they could be connected to make parallel induction coils, with or without a center connection and with or without a center tap, at the same time (with who knows, what types, or how many possible uses), or left separate to make a capacitor, or used as two parallel inductors.
Or make a coiled wire and then, coil the coiled wire, or wind the coiled, coiled wire again, around a core, or center tap, or any other arrangement(s) – basically letting the mind keep wondering, and keep testing and calculating…..
Want more?
Have they ever tried regular material induction cores, with open ends, or closed at one, or at both ends, even tapped in different ways etc, spiraled Inside of differently shaped (circular, triangular, etc…), solid molded plastic, or other materials, etc, etc, etc…..?
These shape ponderings might lead to some wiled stuff!!!
Since there will always be new things!
Thanks for thinking/pondering with me!

Example: On the surface of circuit board, etch a twin spiral, with two conductors running parallel to each other as they spiral toward the center, with a solder hole at its’ end, or at a location in it, so they could be connected to make parallel induction coils, with or without an inner end connection and with or without a center tap, at the same time (with who knows, what types, or how many possible uses), or left separate to make a capacitor, or used as two parallel inductors, which would probably work and behave like a tank circuit, and could be adjusted by how the lines are spaced, and by how many time each is wound, or maybe even a type of antenna, or set of antennas.

Have they ever tried standard material and/or other material, induction cores, made with open ends, closed at one, or at both, tapped in different ways, spiraled in different shapes (circular, triangular, etc…), or coated with molded plastic, at different thicknesses, etc, etc….?

To me, learning from a book is basically memorizing what is already known, but real learning happens when your imagination kicks-in!

Thanks for thinking/pondering with me, and I hope it gets and keeps you wondering too!!!
