I am familiar with the basics of a voltage divider network from what I have learned in my readings. I wonder if there is a practical application for such a circuit to be used dynamically. What I mean by dynamically is that the potential difference across a segment of the voltage divider network would be independent of the other segments or does the voltage divider network have to be specifically designed for the circuit it's going to be used for.
An example would be a 15V source connected to a series of three resistors of equal resistance. In such a configuration there would be 5V across each resistor giving you access to a choice of 5V, 10V or 15V. But if you were add anything to the circuit it would effect the overall resistance and therefore the voltage across all the resistors would change meaning you would have to go back and change a resistor to balance it all out again.
Is this the only possible way to use a voltage divider network?
