In Kirchhoff’s first law, Σi=0 at the junction is based on the law of conservation of charge.
This law states that charge can neither be created nor be destroyed; it can only be transferred from one system to another.
Hence, the correct option is (B).

In Kirchhoff’s first law Σi=0 at the junction is based on the law of ...
Explanation:
Kirchhoff’s first law:
- Kirchhoff's first law, also known as the junction rule or the law of conservation of charge, states that the total current entering a junction in a circuit must be equal to the total current leaving the junction.
- Mathematically, it can be represented as Σi = 0, where Σi represents the sum of currents at the junction.
Conservation of charge:
- The law of conservation of charge states that the total electric charge in a closed system remains constant over time.
- This means that charge can neither be created nor destroyed, only transferred from one object to another.
Relationship between Kirchhoff’s first law and conservation of charge:
- Kirchhoff’s first law is based on the principle of conservation of charge because the total charge entering a junction must be equal to the total charge leaving the junction.
- This ensures that charge is conserved in a circuit and there are no violations of the law of conservation of charge.
Conclusion:
- Kirchhoff’s first law, Σi = 0 at the junction, is based on the law of conservation of charge.
- By following this law, we can analyze and understand the flow of current in a circuit while ensuring that charge is conserved throughout the system.
