*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

ReplyDeleteI really loved reading your blog. It was very well authored and easy to understand. Unlike other blogs I have read which are really not that good.Thanks alot! 여유증 수술

ReplyDeleteA nice explanation thanks.
