Working of linear variable differential transducer (LVDT) is based on the principle of variable_____________________?
Correct answer: C. Mutual inductance
- A. Capacitance
- B. Resistance
- C. Mutual inductance
- D. None of these
Explanation
An LVDT has a movable ferromagnetic core that changes the mutual inductance between its primary and secondary coils. The resulting differential voltage indicates linear displacement.
