Formulate the second Kirchhoff rule. What is the consequence of this rule? How many independent equations

Formulate the second Kirchhoff rule. What is the consequence of this rule? How many independent equations can you make using Kirchhoff’s second rule?

With the chosen positive direction of bypassing the circuit, the algebraic sum of the EMF in this circuit is equal to the algebraic sum of the products of the currents in it and the resistances along which these currents flow. This rule is a consequence of the law of conservation of energy. The number of independent equations obtained on the basis of the second Kirchhoff rule is equal to the number of elementary contours in the circuit.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
