Kirchhoff's second law
Kirchoff's second law
The algebraic sum of all the potential across a closed loop is zero. This law is also known as Kirchhoff's Voltage law (KVL)
-
Change in Potential in traversing a resistance is -iR
-
Change in Potential in the opposite direction is iR
-
Traversing an e.m.f source from negative to positive terminal is -E
-
-
While in the opposite direction is E
