Question

explain kirchhoff s law​

Answer 1

Answer:

in an electric network the algebraic sum of the currents in all the branches that meet at any point is zero.

Explanation:

Answer 2

Answer:

Kirchhoff Law;

Kirchhoff's circuit laws are two equalities that deal with the current and potential difference in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.

Explanation:

Formula;

Kirchhoff's Current Law (KCL) is Kirchhoff's first law that deals with the conservation of charge entering and leaving a junction. In other words the algebraic sum of ALL the currents entering and leaving a junction

must be equal to zero as

: Σ IIN = Σ IOUT.

Example;

Let's take as example the following circuit. It has two loops, A and B, and two nodes, C and D. With the arrows is defined the positive flow of the electrical current.

Importance;

Kirchhoff's laws, one for voltage and one for current, determine what a connection between circuit elements means. These laws can help us analyze this circuit. The places where circuit elements attach to each other are called nodes. At every node, the sum of all currents entering a node must equal zero.
