Question

Conservation of charge and conservation of energy are respectively the basis of

• A. Joule's law and Ampere's circuital law
• B. Gauss' law and Ohm's law
• C. Kirchhoff's junction rule and loop rule
• D. Coulomb's inverse square law and Gauss' law
• E. Joule's law and Ohm's law

Answer 1

The Correct Option is C

Kirchhoff’s first law (junction rule) states that the sum of currents entering a junction is equal to the sum of currents leaving the junction. This is based on the principle of conservation of charge. Kirchhoff’s second law (loop rule) states that the sum of the potential differences (voltages) around any closed loop is zero. This law is based on the conservation of energy in the circuit. Therefore, the conservation of charge and energy is directly related to Kirchhoff’s junction rule and loop rule.

The correct option is (C) : Kirchhoff's junction rule and loop rule

Answer 2

Kirchhoff's laws are based on fundamental conservation principles: 

1. Kirchhoff's Junction Rule:
This rule states that the total current entering a junction equals the total current leaving it.
It is based on the conservation of charge. 
 
2. Kirchhoff's Loop Rule:
This rule states that the total energy gained and lost by a charge around a closed loop is zero.
It is based on the conservation of energy. 

Final Answer: \( \boxed{\text{Kirchhoff's junction rule and loop rule}} \)
