Kirchoff's Law

Kirchhoff's Law is an analysis of such a system uses two properties of electrical networks or two equalities that deal with the current and potential difference in the lumped element model of electrical circuits.

1. All current flowing into a junction must flow out of it.

2. The sum of the products IR ( I is current and  R is resistance ) around a closed path is equal to the total voltage in the path.
