Kirchoffs Law

Two laws governing electric networks in which steady currents flow. The sum of all the currents at a point is zero and the sum of the voltage gains and drops around any closed circuit is also zero.t.

 

Kirchhoff's First Law

• This law is also called Kirchhoff's current law, Kirchhoff's point rule and Kirchhoff's first rule.
• The principle of conservation of electric charge implies that, at any point in an electrical circuit, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point.

 

Kirchhoff's Second Law

• This law is also called Kirchhoff's voltage law, Kirchhoff's loop rule and Kirchhoff's second rule.
• The principle of conservation of energy, states that the total inflow of energy into a system must equal the total outflow of energy from the system, plus the change in the energy contained within the system. So therefore this implies that the directed sum of the electrical potential differences around a circuit must also sum to zero.
