The SI unit of inductance is the
Correct answer: A. henry
- A. henry
- B. weber
- C. tesla
- D. farad
Explanation
One henry is the inductance of a coil in which a current changing at one ampere per second induces a back emf of one volt. The weber measures magnetic flux and the tesla flux density, while the farad belongs to capacitance. Getting these four units straight is worth a mark on its own in most papers.

About Faraday's Law
Faraday's law states that an induced electromotive force equals the rate of change of magnetic flux linkage through a circuit. Questions cover changing field, area, angle or motion, the negative sign associated with Lenz's law, and the distinction between induced emf and the current that may flow in a closed circuit.
