GENERAL KNOWLEDGE

Detailed explanation-1: -John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947. Shockley introduced the improved bipolar junction transistor in 1948, which entered production in the early 1950s and led to the first widespread use of transistors.

Detailed explanation-2: -The only person to win two Nobel Prizes in physics was John Bardeen, first in 1956 for the transistor, and then in 1972 for his theory of superconductivity.

Detailed explanation-3: -The invention of the transistor, which has had a profound impact on the electronics industry, was first developed in 1948. This moment marked the dawn of the electronic age.

Detailed explanation-4: -Invention of the transistor On December 23, 1947, Bardeen and Brattain were working without Shockley when they succeeded in creating a point-contact transistor that achieved amplification.
