I can calculate the volt drop over a given resistor (in a series circuit) using Ohms and Kirchoff's laws. e.g. figure below...
**broken link removed**
but for the life of me I cannot seem to reverse engineer the formula to calculate values for two unknown resistors with known volt drop values.
**broken link removed**
How do I calculate the values for resistors R1 and R2, to give me an output voltage on Potentiometer VR1 of between 2V and 4V with the value of VR1 = 10kΩ, supply voltage = 5V (Output form PIC micro controller).
I want to use this output voltage to drive a IRFP450 N-Channel MOSFET. According to the datasheet my VGS is 2V (min) and 4V (max).
Thank you
