Calculation Formula

I_Norton = V_source / R_source

R_Norton = R_source // R_load = (R_source * R_load) / (R_source + R_load)

Where:
I_Norton = Norton equivalent current source (A)
V_source = Source voltage (V)
R_source = Source resistance (Ω)
R_Norton = Norton equivalent resistance (Ω)
R_load = Load resistance (Ω)

What is Norton Theorem?

Norton's theorem states that any linear electrical network with voltage sources and resistances can be replaced at terminals A-B by an equivalent current source I_N in parallel with a resistance R_N.

How to Use This Calculator

  1. Enter the source voltage (V) of your circuit
  2. Enter the source resistance (R) of your circuit
  3. Enter the load resistance (R_L) that you want to analyze
  4. Click the "Calculate" button to compute the Norton equivalent

Working Principle

The calculator uses the following formulas:

  • Norton Current (I_N): I_N = V_source / R_source
  • Norton Resistance (R_N): R_N = (R_source * R_load) / (R_source + R_load)

Example

For a circuit with a 12V source and 6Ω internal resistance, and a load resistance of 3Ω:

I_N = 12V / 6Ω = 2A

R_N = (6Ω * 3Ω) / (6Ω + 3Ω) = 2Ω

Applications

Norton theorem is particularly useful for:

  • Analyzing complex circuits with multiple sources
  • Designing electronic circuits with variable loads
  • Understanding circuit behavior under different load conditions
