According to Kirchhoff’s Junction Rulea)At any junction of circu...
Explanation:Kirchhoff’s junction rule is based on the principle of conservation of charge. For steady currents, there can be no accumulation of charge in a junction. The currents entering a junction bring charge to the junction and the currents leaving a junction carry away the charge brought to the junction.

According to Kirchhoff’s Junction Rulea)At any junction of circu...
Explanation:
1. Introduction:
Kirchhoff's Junction Rule, also known as Kirchhoff's Current Law (KCL), is an important principle in circuit analysis. It states that the sum of currents entering and leaving a junction (or node) in an electrical circuit must be equal to zero.
2. Understanding Kirchhoff's Junction Rule:
Kirchhoff's Junction Rule is based on the principle of conservation of charge. At any junction in a circuit, charge is conserved, which means that the total amount of charge entering the junction must be equal to the total amount of charge leaving the junction.
3. Currents Entering and Leaving a Junction:
In a circuit, current is the flow of electric charge. When we consider a junction in a circuit, there can be multiple branches or paths through which current can flow. Some currents may be entering the junction, while others may be leaving the junction.
4. Application of Kirchhoff's Junction Rule:
According to Kirchhoff's Junction Rule, the sum of currents entering and leaving the junction must be zero. This can be mathematically represented as follows:
∑Iin = ∑Iout
where ∑Iin represents the sum of currents entering the junction and ∑Iout represents the sum of currents leaving the junction.
5. Explanation of Answer:
The correct answer to the given question is option 'D': At any junction of circuit elements, the sum of currents entering the junction must equal the sum of currents leaving it.
This is because of the conservation of charge. The total amount of charge entering a junction must be equal to the total amount of charge leaving the junction. Since current is the rate of flow of charge, the sum of currents entering the junction must be equal to the sum of currents leaving the junction.
6. Conclusion:
Kirchhoff's Junction Rule, or Kirchhoff's Current Law, is a fundamental principle in circuit analysis. It states that the sum of currents entering and leaving a junction in an electrical circuit must be equal to zero. This principle is based on the conservation of charge and is widely used in analyzing and solving complex circuits.
