Tesla Unit of magnetic flux density, equal to one weber per square
metre of circuit area.
Volt Unit of electric potential. The difference of electric potential
between two points of a conducting wire carrying a constant current
of one ampere, when the power dissipated between these points is
equal to one watt.
