Note 1: V/m (volt per meter) is the standard unit of electric field (E-field) strength. An E field of 1 V/m is represented by a potential difference of 1 V which is existing between two points that are 1 m apart.

Note 2: The Tesla (symbol: T) is a derived unit of the magnetic induction (also, magnetic flux density) in the International System of Units and one tesla is equal to one weber per square metre.
