What is the formula to figure out the resistor value in a 555 timer?
It depends upon how you connect the timer up!
The basic configuration for an astable multivibrator is R1, R2, and C1.
Go to National Semiconductor's website: http://www.national.com
and download a datasheet for the LM555.
if I have a pulse generator with a 10kHz and a duty cycle of 80% and a capacitor of 0.01uf. what would the formula be for finding the resistor values?
I am not quite sure what you mean. Please refer to the formula you plan to use.

i think it is an output
