Norton current calculator
Calculate Norton equivalent current from short-circuit analysis, load removal tests, or Thevenin parameters for DC and AC circuits.
short-circuit current calculator
Norton's current Short-circuit current flowing out of one pair of terminals of the circuit as described in Norton's Theorem. It is the current available at an ideal source in Norton equivalent circuit that is supplied in parallel form. One resistor. The value may be measured as the short-circuit output or derived as a Thevenin equivalent conversion.
Formula & Table Summary:
From Thevenin: I_N = V_TH / R_TH
sequivalent source current formula
By using Norton Current Calculator, we can compute the Norton equivalent current Nof a circuit using Norton Theorem. According to this Theorem by Norton any electrical network can have any number of voltage sources, current sources and resistances can be replaced by a current source in parallel with some resistance. connected in parallel to an ideal current source including one resistor. I Nis was decided by actual measurement of the short-circuit current at the output terminals or transfomation of Thevenin parameters in IN = VTH / RTH. This technique finds wide application in simplifying the analysis of circuits, matching of loads and assessments of how a network will perform in different conditions. loading conditions. Complex networks involving AC and DC systems can be analyzed with much ease by the use of the Norton equivalent and still obtain the same terminal behavior. This calculator allows not only the direct calculation of short-circuit, but also Thevenin-to-Norton conversion to provide utmost flexibility.

Frequently Asked Questions - Norton current calculator:
What is Norton current?
Norton current is the short-circuit current at the output terminals of a circuit as per Norton’s Theorem.
How do I find Norton current directly?
Short the load terminals, measure the resulting current—this is the Norton current (I_N).
How can I calculate Norton current from Thevenin parameters?
Use I_N = V_TH / R_TH, where V_TH is Thevenin voltage and R_TH is Thevenin resistance.
Is Norton current the same as short-circuit current?
Yes, for linear circuits, Norton current equals the short-circuit current across the load terminals.
Can I use Norton’s theorem for AC circuits?
Yes, Norton’s theorem applies to both AC and DC circuits, using impedance instead of resistance in AC.
What is the relationship between Norton and Thevenin equivalents?
They are dual forms—Norton’s ideal current source in parallel with R equals Thevenin’s voltage source in series with R.
Why use Norton’s theorem in analysis?
It simplifies circuit analysis, making it easier to evaluate different loads and calculate currents.
Does source type affect Norton current?
Yes, the value depends on the source and network resistances or impedances in the original circuit.
How do I measure Norton current safely?
Use appropriate current meters rated for the circuit’s voltage and expected short-circuit current.
Can Norton current be zero?
Yes, if the network cannot deliver current to the shorted terminals, I_N will be zero.
