# Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL)

### Fondamental : Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL)

These laws are written in the form (see figure) :

• Kirchhoff's current law :

• Kirchhoff's voltage law :

Kirchhoff's current law (KCL) and Kirchhoff's voltage law (KVL)

### Complément : Pouillet's law

The KVL gives :

We deduce the intensity in the circuit (this is the Pouillet's law) :
