A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.

A Carey-foster's bridge is a modified version of the meter bridge (wheatstone bridge or potentiometer). It can be used to find out the average resistance per unit length of the meter bridge wire and hence find out the unknown resistance. It is more accurate and more sensitive than a meter bridge.

A meter bridge is called so because it is a bridge-like structure that measures electrical resistance using the principles of a Wheatstone bridge. It consists of a one-meter-long wire mounted on a base, allowing for the determination of unknown resistances by balancing the circuit. The term "meter" specifically refers to its length, which facilitates the measurement process.
A meter bridge is preferred over a voltmeter for measuring resistance because it provides a direct comparison between two resistances, allowing for more accurate measurements by eliminating the impact of internal resistance and calibration errors found in voltmeters. Additionally, a meter bridge can measure very low resistances more effectively and does not require a power supply, making it suitable for precise laboratory work. It also allows for the determination of unknown resistances using the principle of balance, which enhances measurement reliability.
A principle is the summary of the description of how something works. A principle is a rule of action or conduct. (Answer for Amer. Gov. Question = Doctrine)
