*Branch current analysis is a method used for calculating current in each branch.***The branch current analysis uses the combination of Kirchoff's current and voltage law to obtain a set of linear equations. These linear equations are then solved to achieve the value of current flowing in branches.**

Follow these steps to solve a circuit using branch current analysis:

- Assign the arbitrary direction of current to all branches.
- Apply Kirchhoff's voltage law to all loops.
- Apply Kirchhoff's current law to all nodes.
- Solve the equations.

The example below provides a clear insight of steps.

### Example: Find all the branch currents in the circuit.

Solution:

Step 1: First of all assign the arbitrary current directions to all branches.

I got for Step 3:

ReplyDelete4V -2I2 +2I3 = 0 .

Sorry that is a typo mistake will correct the first line of step A. The second line is correct however.

ReplyDeletejust a combination of kcl and kvl.

ReplyDeletewhen we take positive sign and when we take negative sign
