Branch current calculator
Easily calculate the current in each branch of a circuit using voltage, resistance, or impedance. Works for DC and AC with accurate results.
parallel branch current calculator
The current which flows through the branch of an electrical circuit is known as a branch current. In parallel circuits, the circuit currents can be calculated one by one with Ohm s Law whereas in general networks, Kirchhoff Current Law is used to make sure that the total of incoming current equals the total outgoing current in any node.
Formula & Table Summary:
Multiple Branches: Use KCL → ΣI_in = ΣI_out
AC Circuits: I_branch = V_branch / Z_branch
dc branch current calculator
By entering the values of current identified by particular paths in a circuit, the Branch Current Calculator computes current in each single branch in a parallel, series-parallel, or complicated topology. A branch is a single pathway between two nodes and it can contain one or more components. In the case of parallel circuit, current through a branch may be calculated by Ohm s law (I = V/R) branch by branch, given that the voltage is assumed to be the same across all branches. Current in series circuits is the same in all components whereas in mixed networks, Kirchhoff Current Law (KCL) and network analysis are engaged. The tool applies to both DC and AC systems, the impedance is used in place of the resistance in AC calculations. It can be used by engineers, students and electricians to load balance, size conductors, check against overload and ensure circuit design is accurate.

Frequently Asked Questions - Branch 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.
