Question

Kirchhoff’s junction rule is based on conservation of

• A. charge
• B. energy
• C. both energy and charge
• D. angular momentum
• E. linear momentum

Hint:

Always use Kirchhoff’s rules for analyzing complex circuits to simplify finding unknown currents and voltages.

Answer 1

The Correct Option is A

Step 1: Kirchhoff’s junction rule (also known as the current law) states that the total current entering a junction equals the total current leaving the junction. 
Step 2: This law is derived from the principle of conservation of charge, ensuring that no charge is lost or created at the junction. 
Step 3: Therefore, Kirchhoff's junction rule is based on the conservation of charge.
