I have a voltage divider that I tried to post, but it won't take it. It starts at the left where you tap off of the circuit 30mA at 300v, go through a resistor, tap off 10mA at 150v, go through another resistor, then all of the voltage is used up, and that end is grounded, go through another resistor (bleeder), tap off -3v at 0 A, go through another resistor, then tap off -5v at 0 A. The bias bleeder current is 60mA. The left side resistor is positive, and the right side (last) resistor is negative. How do I find the values of the resistors, and how can I have a negative voltage?
