i hear you can put them in series.

but, i also heard that you divide them

i thought if you put those two the total capacity is 200? why does it go down?

I'm new and that confuses me

EDIT:

i want to try connecting a few capacitors to a resistor and then an led to see how long it takes for the led to go out. to learn a little bit

Capacitors in series or parallel is opposite to resistors in series
have a read through this tutorial...

thankyou. i have one question. what is the point of capacitors in series if it equals less like above where 2 100uf would equal 50 uf? is this to get more of a exact desired number?

you may not have a 50uF handy but do have a bunch of 100uF caps

or you just need to know the effects of a set of caps in parallel or series
they could all be different values, when doing circuit design
say one could be an actual capacitor where the other is the capacitance between 2 circuit tracks. This becomes critical when dealing with VHF and higher RF electronics,
where very small capacitances can have large effects on how the circuit operates

thankyou very much dave
