Voltage Divider Calculator. To use this voltage divider resistor calculator a user must enter the value of the input voltage vin. R1 is the resistance of the 1st resistor r2 is the resistance of the 2nd resistor v out is the output voltage.
The voltage divider resistor calculator calculates the value of the resistor r2 of the voltage divider network based on the value of resistor r1 the input voltage vin and the output voltage vout this resistor value of r2 is calculated by the formula r2 vout r1 vin vout. The voltage divider calculator calculates the output voltage of the voltage divider network based on the value of resistor r1 resistor r2 and the input voltage vin this output voltage which is the voltage that is dropped across resistor r2 is calculated by the formula vout vin r2 r1 r1. V in is the input voltage.
The formula for calculating the output voltage is based on ohms law and is shown below.
R1 is the resistance of the 1st resistor r2 is the resistance of the 2nd resistor v out is the output voltage. Voltage divider calculator 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. It takes the inputs of voltage source and resistance to give accurate voltage in a circuit. According to this formula the resistor with the greater resistance value will drop more.
