**Kirchhoff's Current Law:**

At any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node.

You can tell which way the current is flowing, and in some cases how much current is flowing in that direction.

**Kirchhoff's Voltage Law:**

the sum of the emfs in any closed loop is equivalent to the sum of the potential drops in that loop.

Ea + Eb + Ec + . . . En = 0.

**Applications :**

- The current distribution in various branches of a circuit can easily be found out by applying Kirchhoff Current law at different nodes or junction points in the circuit.
- After that Kirchhoff Voltage law is applied, each possible loop in the circuit generates algebraic equation for every loop.

**By solving all these equations, one can easily find out different unknown currents, voltages and resistances in the circuits.**

*So it would be helpful in electrical engg while designing circuits.*
