Final answer:
The 1-turn/2-turn joining rule, also known as the 12/23 rule, is a concept used in electrical circuits and is a part of Kirchhoff's first rule, also known as the junction rule. It states that the sum of currents flowing into a junction is equal to the sum of currents flowing out of the junction.
Step-by-step explanation:
The 1-turn/2-turn joining rule, also known as the 12/23 rule, is a concept used in the field of electrical circuits and is a part of Kirchhoff's first rule, also known as the junction rule. It states that the sum of currents flowing into a junction is equal to the sum of currents flowing out of the junction.
For example, if we have a junction where I₁ is flowing in and I₂ and I₃ are flowing out, the equation would be: I₁ = I₂ + I₃.
This rule is used to apply the conservation of charge in a circuit and ensure that the current is conserved at junction points.
