Electrical inventors

List below with attached picture with their Biodata. They are very popular electrical inventors even up to the present time, one of the remarkable was their family names use as units in the formulas of ohms law.

Ohms Law formula
Voltage(v) = Current(i) times resistance(r)


addtional formula
Power(p) = Current(i) times voltage(v)

The unit of voltage is volt while current is ampere then resistance is ohms and power is watts.
