voltxsecond is equal to:
Correct answer: C. henry
- A. gauss
- B. weber
- C. henry
- D. tesla
Explanation
Henry is the unit of inductance, which is equal to 1 volt*sec/ampere, which is the voltage across a conductor directly proportional to the rate of change of current.

About Magnetic Flux
Magnetic flux measures the magnetic field passing through a surface, calculated for a uniform field as Φ = BA cos θ, where θ is the angle between the field and the surface normal. Questions involve area, field strength and orientation, the weber as its unit, and the distinction between flux and magnetic field.
