in a closed circuit that sum of total emf is equal to the sum of the​

Answer 1

In a closed circuit the algebraic sum of currents of conductors meeting at a point is equal to zero.

Explanation:

• Closed circuits can be analysed by using Kirchhoff’s laws.
• This law states that at any junction point in a circuit, the total sum of currents flowing in and out is equal.
• Mathematically it cab be expressed as:  
• ∑ n  - k  =  1  I k  =  0
• Where Ik is the current of k, and n is the total number of wires flowing into and out of a junction.
• In an electrical circuit the Kirchhoff’s junction rule states that, the sum of current flowing in and pout of a junction is same.
• Similarly in a close circuit the algebraic sum of currents of conductors meeting at a point is equal to zero.
