Q. State Kirchoff's second law in electricity?
Kirchoff's second law (voltage law) the algebraic total of the products of resistance as well as current in each part of any closed circuit is equal to the algebraic sum of the emf's in that closed circuit. This law is a result of conservation of energy.
