Hydraulic analogy of diode

It’s John Ambrose Fleming (1849-1945), a British engineer, who invented the first diode in 1904, in the form of an electron tube. Later, with the development of semiconductor technology, the diode became a dipole consisting of two substrates: one, rich in free electrons, and of type N, the other deficient in electrons, and of type […]
