I need to design a simple resistor divider circuit with the following specs:
input voltage 15v output from divider 10v and should meet these specs with a load from 0 to 0.1mA
I have to determine the value resistors. so far I have R1 150k and R2 300k.
But that is with 2 resistors, if I add a load on there now, it obviously reduces the output voltage and if I add in a current source I get an output voltage of nearly zero.
What are the variances? You can't design it with out knowing what they are. Is 15v equivalent to 15.000000000000 Volts? or is it 15+- 0.5 volts?
You have one equation that has to meet two answers. Can't do it.
Say 10v =10 +- 0.5 then you can do something, you have two equations two unknowns.
The exact question is:
Design a voltage divider with the following specs:
A. use an input voltage source of 15v b. deisgn voltage divider to output 10volts with a tolerance of +/- 2% c. it should meet this spec with al oad from 0-0.1mA d. determine the value and tolerance of the resistors
I actually changed my values on the resistors to 2k and 4k and I think I got what I needed.
