The transistor was invented by _.
Correct answer: A. John Bardeen
- A. John Bardeen
- B. Henry
- C. John Henry
- D. Joule
Explanation
The invention of the transistor is credited to a team of researchers at Bell Laboratories in 1947. The team, led by William Shockley, along with John Bardeen and Walter Brattain, successfully demonstrated the first working transistor. Their invention revolutionized electronics by replacing bulky and less reliable vacuum tubes, paving the way for the development of smaller, more efficient, and more reliable electronic devices. The three scientists were awarded the Nobel Prize in Physics in 1956 for their groundbreaking work on the transistor.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
