The correct answer is: D. Any of the above.
A linear variable differential transformer (LVDT) is a type of transducer that can measure linear displacement, velocity, and acceleration. It consists of a primary coil, a secondary coil, and a magnetic core. The primary coil is energized with an alternating current, which creates a magnetic field. The magnetic core is moved through the magnetic field, which induces a voltage in the secondary coil. The voltage in the secondary coil is proportional to the displacement of the magnetic core.
The LVDT can be used to measure displacement by measuring the voltage in
