Enter the applied current (amps) and the total resistance of the circuit (ohms) into the calculator to determine the Applied Voltage. 

Applied Voltage Formula

The following formula is used to calculate the Applied Voltage. 

Va = Ac * R

Variables:

  • Where Va is the Applied Voltage (volts)
  • Ac is the applied current (amps) 
  • R is the total resistance of the circuit (ohms) 

How to Calculate Applied Voltage?

The following two example problems outline how to calculate the Applied Voltage.

Example Problem #1:

  1. First, determine the applied current (amps). In this example, the applied current (amps) is measured to be 30.
  2. Next, determine the total resistance of the circuit (ohms). For this problem, the total resistance of the circuit (ohms) is calculated to be 20.
  3. Finally, calculate the Applied Voltage using the formula above: 

Va = Ac * R

Inserting the values from above and solving the equation with the imputed values gives: 

Va = 30* 20 = 600 (volts)


Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

applied current (amps) = 10

total resistance of the circuit (ohms) = 5

Entering these values into the formula or calculator above gives us:: 

Va = 10 * 5 = 50 (volts)
