Question

What was kirchoffs second law?

Answer 1

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 complete traversal of a mesh (closed loop) is zero”, i.e.

V = 0

Answer 2

second law of kerchhoffs was that the sum of potential difference in a loop of a circuit carrying current is always equal to null.
