Transistors are powerful devices because of their ability to control the current flowing through a circuit (current controlling device), which is generated by the flow of electrons and holes. Read the following points to know more about transistor: In simpler terms, a transistor is basically a regulator of the flow of electric signals. To resolve this problem, the three American physicists John Bardeen, Walter Brattain, and William Shockley invented a compact-sized and efficient semiconductor device called point-contact transistor at Bell Labs in December.Ī transistor is a kind of semiconductor that is used as a conductor and insulation of electric current or voltage.

On this page, we will learn about the following: These tubes were larger, required higher operating voltage, high power consumption meant high heat generation which in turn affected the life of the tube due to its low efficiency.

This tube was used to control the electric current. If we read the history of electronic devices, one of the most important components of these devices was a vacuum tube (electron tube).
