This is a voltage divider video tutorial. This video explains about the voltage divider and the use of voltage divider. Voltage divider is the circuit that is used to reduce voltage using resistor. The voltage divider can be used in many things such as to create a point control voltage or generate reference voltage. The following equation defined the output voltage of the voltage divider :
Vout=Vin x (Rbottom/(Rbottom+Rtop))
The voltage divider is different from the voltage regulator power supply. Here is the video:
