Concept:
Kirchoff’s second law: According to Kirchhoff’s voltage law (KVL), the algebraic sum of all the voltages around any closed path is zero. It is based on the conservation of energy.
- This law is also known as loop rule or voltage law (KVL) and according to it “the algebraic sum of the changes in potential in the complete traversal of a mesh (closed-loop) is zero”, i.e. Σ V = 0.
- This law represents “conservation of energy” as if the sum of potential changes around a closed loop is not zero, unlimited energy could be gained by repeatedly carrying a charge around a loop.
- If there are n meshes in a circuit, the number of independent equations in accordance with the loop rule will be (n - 1)
