To determine the current flowing in each branch of the network using Kirchhoff's laws, we can apply Kirchhoff's current law (KCL) at each node in the circuit.
1. Identify all the nodes in the circuit where the branches meet. Label each node with a variable (e.g. A, B, C, etc.).
2. Apply KCL at each node by summing up the currents entering and leaving the node. The sum of the currents entering the node should equal the sum of the currents leaving the node.
3. Write down the equations for each node based on KCL. For example, at node A, the equation would be: I1 + I2 = I3, where I1, I2, and I3 are the currents flowing in the branches connected to node A.
4. Solve the system of equations to find the values of the currents in each branch.
By following these steps and applying Kirchhoff's laws, you can determine the current flowing in each branch of the network.

Kirchhoff's Current Law (KCL) states that the algebraic sum of currents entering and leaving any node in a circuit is zero.
Step 1: Label Currents
Label the currents flowing in each branch as follows:
- I1: Current flowing from node A to B
- I2: Current flowing from node B to C
- I3: Current flowing from node C to A
Step 2: Apply KCL to Node A
At node A, the sum of currents entering must equal the sum of currents leaving:
```
I1 - I3 = 0
```
Step 3: Apply KCL to Node B
At node B, the sum of currents entering must equal the sum of currents leaving:
```
I1 + I2 - I3 = 0
```
Step 4: Solve for Currents
Subtract Equation (1) from Equation (2) to eliminate I3:
```
I2 = I1
```
Substitute I2 = I1 into Equation (1):
```
I1 - I1 = 0
```
Therefore, I1 = I3 = 0.
Substitute I1 = 0 into Equation (3):
```
I2 = 0
```
Therefore, all currents in the network are zero.
Note: This result may seem counterintuitive, but it is a valid solution to the system of equations. It indicates that there is no current flow in any of the branches of the network.
