Wheatstone bridge is an arrangement of _________ resistors used for accurate measurement of resistance.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 4.
A Wheatstone bridge is an arrangement of four resistors used for the accurate measurement of resistance.
The bridge consists of a series circuit with four resistors arranged in a diamond shape, where two resistors are in each of the two branches. The bridge is used to compare an unknown resistor with known resistors to determine its value precisely.
The Wheatstone bridge was invented by Samuel Hunter Christie in 1833 and later popularized by Samuel Hunter Wheatstone in 1843. It remains a fundamental tool in electrical engineering and physics.
