Does anyone know how you can work and calculate the value of a capacitor in an rc circuit if you have a resistor of 1 kilo ohm with a cut off frequency of, for example, 2.5 kHz?
Cutoff frequency is subject to how you define it. It tends to be simplified as a two-line graph with zero slope and then a ramped slope. In reality it is on continuous gradual curve. But traditionally, cutoff frequency -3dBi which is half the power (or 70.7% the magnitude). Then that is this formula:

If you have a low pass filter rc circuit (with a cut off frequency of 2.5kHz) with a 1 kilo ohm resistor, how do you theoretically calculate the value of the capacitor?
If you have a low pass filter circuit diagram (with a cut off frequency of 2.5kHz) with a 1 kilo ohm resistor, how do you calculate the value of the capacitor required to meet the frequency response?
umm, micro, nano, pico, milli, etc...these are just standard unit prefixes. I'm sure you're familiar with millimeters, centimeters, meters and kilometers right? Basically that's just 1/1000 of a meter, 1/100 of a meter, 1/1 of a meter and 1000/1 of a meter right? Or in other words 1m * 10^-3 for millimeter (or mm). So a micrometer is 1/1000000 of a meter (10^-6 meter), or a micrometer is 1/1000 of a millimeter. A nanometer is 1/1000 of a micrometer and a picometer would be 1/1000 of a nanometer.
Here's one of hundreds of sites that explain unit prefixes: http://www.telecomabc.com/p/prefix.html
