Explanation:

- The Weber is the unit of magnetic flux in the International System of Units (SI). When measuring how much magnetic flux changes over time, you'll get a voltage.

- Volt : A volt is the unit of electric potential or electromotive force. One Weber per second is indeed equivalent to one volt. Hence, the unit describes the generation of electromotive force by magnetic flux change.

- Ampere: This is a unit of electric current, and it would not be equivalent to Weber per second.

- Coulomb: This measures the quantity of electric charge, not magnetic flux or its rate of change.

- Ohm: This unit measures electrical resistance, and it does not relate directly to Weber per second.
