How to Calculate Ripple Current?
How do I calculate the ripple current a capacitor will experience for a given circuit?
For example, let's say I have a smoothing capacitor on the output of a full-wave bridge rectifier (120VAC, 60Hz) ...

Which manufacturer's logo is this?
I'm trying to identify the manufacturer (and hopefully part number) for these capacitors.
My guess is they're standard aluminium electrolytics, rather than something fancy like alupoly, but I can't ...

What is this capacitor?
Can anyone confirm what the markings on this capacitor mean?
I think it's a 560 μF capacitor, but I am used to seeing that on the first row of similar devices.
For voltage, I believe it's a 35 V ...

What is the purpose of these different-value capacitors? [duplicate]
I guess I am trying to figure out why we wouldn't just consolidate these into one single 22.11uF capacitor.
My initial understanding was that each capacitor was better at filtering certain frequencies,...

How to calculate the voltage out of capacitor?
In the above image a small part of a large circuit I'm trying to understand.
V1 : 220v @50
D1 : Any diode like 4007
R1 : 270k
R2 : 16k
C1 : 10u to 100u
M1 : Voltmeter
Vout = (Vs*R2) / (R1+R2)

Why conductor having charge(let say 1C) have tremendous potential but same conductor used in capacitor have low voltage?
When we talk about electrolytic capacitors or the supercapacitors (EDLC), then we know that we can store large amount of charges in it.
Since in electrolytic capacitors the aluminum plate acts as ...

I have a height problem (with my switching regulator on a height constrained PCB)
I was planning to use this part (datasheet) (basically MC34063 with thermal shutdown,) but I don´t have enough room above the PCB.
I need to keep the components under 2.2mm.
According to my ...
