Voltage divider

[Patrick Chung]

Voltage divider is just two resistor connected is series, but powerful tool for calculating electrical potential of some nodes. Instead of solving system of equations, all we need to do in order to calculate output voltage of an voltage divider is to find quotient of resistor value and sum of two resistors that makes voltage divider, and then to find product of this quotient and input voltage.
