what resistors should i connect in parallel to get 3.3k and 33k?

[deathbringer07]

and what capacitor values should i connect in series to get 470pF?

What resistors and capacitors have you got?

Two 1nF caps in series will give 500pF, which is near enough to 470.

Three 10K, two 6.8K or a 10K and 4.7K in parallel will give near enough to 3.3K and three 100K, two 68K or a 100K and 47K will give approx 33K.

whats the value of 1nF in uF or pF?

[MartyMart]

whats the value of 1nF in uF or pF?

1nf = 1000pf or 0.001uf
100nf = 100,000pf or 0.1uf

Here's why you should choose the values that were suggested for you (a "teach a man to fish..." sort of thing):

(from an older post)

When combining capacitors in parallel (or resistors in series), it's easy; the values of the individual components are added.
When combining capacitors in series (or resistors in parallel), it's different.


A handy thing to keep in mind when combining caps in series is that connecting two caps of the same value in series will result in a total capacitance equal to one half the original value.  (This is also true for two resistors of the same value connected in parallel- total resistance is one half the original resistance of each one.)


This site (click) has several programs that will do the calculations for a variety of applications, and one of those is a parallel resistor calculator (in menu on the left).  You can use this to calculate caps in series if you keep your units straight.
You'll have to guess and check your way to a practical combination for your use, but it should be a quick process.

google is always on hand and easier to remember. just type in something like 40microfarads to picofarads and it will tell you.
