**Kirchhoff's Laws**

Kirchhoff’s Laws are Conservation Rules of a circuit.

Kirchoff's 1^{st} Law (The Junction Rule) states that the total current that enters a junction is equal to the total current that leaves the junction.

In the above diagram the current i_{1} is equal to the sum of currents i_{2}, i_{3}, and i_{4}.

Here, the **charge** is conserved.

Kirchoff's 2_{nd} Law (The Closed Loop Rule): Conservation of energy. The sum of voltages around a closed network is zero.

Can be also stated as 'the sum of emfs in a closed loop is equivilent to the sum of the potential drops in the loop'.

An example of a closed loop

Here, the **energy** is conserved.
