Voltage Drop Across Resistor Calculator & Formulas

RESISTOR DROP ACROSS RESISTOR CALCULATOR

  Vin : (Volts)

    R1: Ω kΩ MΩ

    R2: Ω kΩ MΩ

         

  Calculations:

The voltage across each resistor in series is inversely proportional to the total equivalent resistance (R1+R2) and directly proportional to the corresponding resistor at which voltage drop is to be calculated. To calculate the voltage across each resistor in a series circuit, we can use the following formula:

V1 = (R1 / (R1 + R2)) x V

V2 = (R2 / (R1 + R2)) x V

where V is the total input voltage or source voltage, R1 and R2 are the resistances of the two resistors, and V1 and V2 are the voltages across the individual resistors.

To simplify this calculation, you can use the voltage drop across resistor calculator tool for two resistors in series. This tool requires input values of the total voltage and the values of the two resistors. The tool then calculates and displays the voltage across each resistor.

It is important to note that this tool only works for two resistors in series. For circuits with more resistors, we need to use a different tool.

RESISTOR DROP ACROSS 3 RESISTOR CALCULATOR

    Vin : (Volts)

      R1: Ω kΩ MΩ

      R2: Ω kΩ MΩ

      R3: Ω kΩ MΩ

           

  Calculations:

The voltage across each resistor in series is inversely proportional to the total equivalent resistance (R1+R2+R3) and directly proportional to the corresponding resistor at which voltage drop is to be calculated.  To calculate the voltage across each resistor in a series circuit, we can use the following formula:

V1 = (R1 / (R1 + R2 + R3)) x V

V2 = (R2 / (R1 + R2 + R3)) x V

V3 = (R3 / (R1 + R2 + R3)) x V

whereas, V is the total input voltage or source voltage, R1, R2, and R3 are the resistances of the three resistors, and V1, V2, and V3 are the voltages across the individual resistors.

To simplify this calculation, we can use this voltage drop calculator tool for three resistors in series. This tool requires input values of the total voltage and the values of the three resistors. The tool then calculates and displays the voltage across each resistor.

It is important to note that in a series circuit, the sum of the voltages across each resistor is equal to the total voltage. Therefore, we can use this property to check the accuracy of our calculations.
