Question

Pick the correct answer from the following two staternents :
(a) Kirchhoff's junction law is based on conservation of charge
(b) Kirchhoff's loop law is based on conservation of energy.

• A. Only (a) is true
• B. Only (b) is true
• C. Both (a) and (b) are true
• D. Both (a) and (b) are false

Answer 1

The Correct Option is C

Kirchhoff's laws are fundamental to circuit analysis:  

(a) Kirchhoff's junction law (also called the current law or KCL) states that the total current entering a junction equals the total current leaving it.  
This is based on the **conservation of charge**—no charge is lost or created at the junction.  

(b) Kirchhoff's loop law (also called the voltage law or KVL) states that the sum of the EMFs and potential differences in any closed loop is zero.  

This is based on the conservation of energy—the total energy gained and lost by a charge around a loop must be zero.  

Therefore, both statements are true.

The correct option is (C): Both (a) and (b) are true
