How does the Kelvin bridge differ from the wheatstone bridge?
kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.
Applications of Carey foster's bridge?
The Carey Foster bridge works on the principle of the wheatstone bridge (potentiometer)which can be used to measure fractional resistance.
How does the Kelvin bridge differ from the wheatstone bridge?
kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
What is the difference between Wheatstone bridge and meter bridge?
WHEATSTONE BRIDGE : A wheatstone bridge is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown compound.Its operation is similar to the original potentiometer. METER BRIDGE : A uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a wheatstone bridge or of a potentiometer.
What is Wheatstone's bridge?
The wheatstone bridge is an instrument used to measure electrical resistance by means of balancing a bridge circuit. The bridge circuit contains two legs, one of which contains the unknown resistance. Variations in wheatstone bridge can be employed to measure inductance, capacitance, and impedance also.

What are the two main types of bridges in electricity?
The two main types of bridges in electricity are Wheatstone bridge and Kelvin bridge. The Wheatstone bridge is used to measure resistance while the Kelvin bridge is used to measure low resistance values. Both bridges are commonly used in electrical and electronic circuit analysis for accurate measurements and fault detection.
In physics what is the use of meter bridge?
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.
What did Charles wheatstone inventions?
Charles Wheatstone invented the concertina, a small musical instrument similar to an accordion. He also invented the Wheatstone Bridge, a device used to measure electrical resistance accurately. Additionally, Wheatstone contributed to the development and improvement of the telegraph system.
What is Difference between ohmmeter and Wheatstone's bridge?
An ohmmeter is a device used to measure the resistance of a component or circuit by passing a current through it and measuring the voltage drop. In contrast, a Wheatstone's bridge is a circuit used to measure an unknown resistance by balancing it against known resistances in a bridge configuration, without passing a current through the unknown resistor. Wheatstone's bridge is more accurate for precise resistance measurements compared to an ohmmeter.
Why the Wheatstone bridge is not used in the laboratory in place of meter bridge?
The Wheatstone bridge is not typically used in laboratories in place of the meter bridge due to its more complex setup and sensitivity to external factors, which can lead to inaccuracies. While the Wheatstone bridge is excellent for precise measurements of resistance, it requires careful adjustment and calibration. In contrast, the meter bridge is simpler, easier to use, and allows for quicker comparisons of resistances using a direct method. Additionally, the meter bridge can accommodate a wider range of resistance values without requiring recalibration.
