Concepts Of Physics MCQ Edition [Volume 2]PhysicsElectric Current in Conductors
Analyze the two statements provided below: (A) Kirchhoff's junction law is based on the conservation of charge. (B) Kirchhoff's loop law is based on the conservative nature of the electric field.
Options
- ABoth A and B are true
- BB is true but A is false
- CA is true but B is false
- DBoth A and B are false
Correct answer
A. Both A and B are true
Step-by-step solution
Kirchhoff's junction law states that the algebraic sum of currents at any junction in a circuit is zero. This implies that charge does not accumulate at any junction, which is a direct consequence of the law of conservation of charge. Thus, statement (A) is true. Kirchhoff's loop law states that the algebraic sum of changes in potential around any closed loop is zero. This is based on the law of conservation of energy. The potential difference is the work done per unit charge by the electric field. Since the electr
