The SI unit of inductance is the
- 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.
