Enter the Thevenin voltage (volts) and the Thevenin resistance (ohms) into the calculator to determine the Norton Current. 

Norton Current Formula

The following formula is used to calculate the Norton Current. 

In = Vt / Rt
  • Where In is the Norton Current (amps)
  • Vt is the Thevenin voltage (volts) 
  • Rt is the Thevenin resistance (ohms) 

To calculate norton current, divide the thevenin voltage by the thevenin resistance.

How to Calculate Norton Current?

The following two example problems outline how to calculate the Norton Current.

Example Problem #1:

  1. First, determine the Thevenin voltage (volts). In this example, the Thevenin voltage (volts) is measured to be 40.
  2. Next, determine the Thevenin resistance (ohms). For this problem, the Thevenin resistance (ohms) is calculated to be 4.
  3. Finally, calculate the Norton Current using the formula above: 

In = Vt / Rt

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

In = 40 / 4 = 10 (amps)

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:

Thevenin voltage (volts) = 60

Thevenin resistance (ohms) = 10

Entering these values into the formula above gives us:: 

In = 60 / 10 = 6 (amps)
