Kirchhoff's Voltage Law (KVL), which states that the algebraic sum of all potential differences in any closed loop is zero, is a direct manifestation of the conservation of:
A. Linear Momentum
B. Mass
C. Energy
D. Electric Charge
Answer: Option C
Solution (By JKSSB Mock Tests)
Kirchhoff's Second Law (KVL) is based on the principle that the electrostatic field is conservative. The work done (energy spent or gained) in moving a unit charge completely around a closed electrical loop must be zero. Therefore, the sum of voltage drops and EMFs is zero. This strictly represents the Law of Conservation of Energy.
Explanation:
For closed pipe, fundamental f = v/(4L) = 340/(4×0.16) = 340/0.64 ≈ 531 Hz, close to 512 Hz, slight difference due to end correction. So fundamental. Approx match, SSC type.
