What is the greatest discovery in the field electronics?
Transistors are another of the most important electrical inventions of all time. Some would argue that they might just be one of the most important discoveries in engineering in general too. Transistors are basically electronic switches that allow current to be turned on and off on demand.
What was the first electronic invention?
relay
The first electronic device ever invented is the relay, a remote switch controlled by electricity that was invented in 1835 by Joseph Henry, an American scientist, although it is also claimed that the English inventor Edward Davy “certainly invented the electric relay” in his electric telegraph c. 1835.

Which scientific theory is most accepted today?
What is an example of scientific theory? One of the most popular scientific theories is Einstein’s Special Relativity, which explains the relationship between space and time for objects moving at a consistent speed in a straight line. The theory also explores a concept known as time dilation.

Where were electronics invented?
In the year 1879, Joseph Wilson Swan was invented as an electric lamp in Britain. The filament of the lamp is carbon & had a fractional vacuum & demonstration of preceded Edison’s in six months. James Clerk Maxwell was a British physicist, and he wrote a treatise on magnetism and electricity in the year 1873.
