Kirchhoffs' Circuit Law

Kirchhoffs law of current and voltage are two laws that are really useful when you are working with circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. 

Kirchhoff's Current Law: This law is also called Kirchhoff's first law, Kirchhoff's point rule, or Kirchhoff's junction rule. It states that all the current going into a node is equal to all the current that goes out from the node. The electrons that flow into the node have to come out from the node as well. The law is based on the conservation of charge whereby the charge is the product of the current and the time.

Kirchhoff's Voltage Law: This law is also called Kirchhoff's second law, Kirchhoff's loop rule, and Kirchhoff's second rule. It says that the sum of all the voltages measured in a circuit equals zero. This law is based on the conservation of energy whereby voltage is defined as the energy per unit charge. 

Uses: Kirchhoffs' circuit law is really important. It could be much easier for you to design circuits, look at circuits and debug circuits if you understand it well.
