Introduction. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.

voltage divider model of the volume control circuit. The main principle of operation is that the circuit acts as a voltage divider (Figure 1, right). One resistor of the voltage divider model is formed by the by series combination of equivalent of R1 and a fraction of R2. The parallel equivalent is formed by remainder of R2 in parallel with R3.

We’re assuming 12 volt supply, although any reasonable value can be used. The base voltage to ground is determined by the divider string of R1 (10K) and R2 (2K) with the applied 12V; 12VxR2/ (R1+R2), which will be 2 volts. The resistor values are kept simple to make this intuitively easy to grasp. The base-emitter drop is going to be .65 to .7
Placement of voltage divider for elevated heater | diyAudio
https://www.diyaudio.com/community/threads/placement-of-voltage-divider-for-elevated-heater.337849/
1. Do I place the voltage divider reference at the pre-Maida pre-regulated B+, or do I put it on the clean post-regulated B+ side? Can the CT of the heater winding inject noise into the clean B+? 2. Also, I saw elsewhere that total R should be in the 300k range. I have a 150k and 30k resistor to make the divider- is that sufficient? (500V rated ...

The output level will be R2/ (R1+R2) of the input. Let's say you wanted to divide the input signal by 3. I'd try to keep the input impedance of the divider at least 1 kΩ, which is R1+R2. R1 of 2 kΩ and R2 of 1 kΩ would divide the input by 3 while maintaining a reasonable input impedance.

A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. The formula for calculating the output voltage is based on Ohms Law and is shown below. where: V S is the source voltage, measured in volts (V), R 1 is the resistance of the 1st resistor, measured in Ohms (Ω).
