# Kirchhoff's Law

- The basic law which states that the sum of currents flowing into any junction of an electric circuit is equal to the sum of currents flowing out of the junction.
- where
**I**_{i}= currents impinging on node

**Kirchhoff's Voltage Law**- The basic law which states that the sum of voltage sources around any closed circuit is equal to the sum of the individual voltage drops across the resistances of the circuit.
- where
**V**_{i}= potential differences around loop
