What is a meter in physics?
In physics, a meter is a unit of length in the International System of Units (SI), equal to the distance that light travels in a vacuum in 1/299,792,458 seconds. It is often used to measure distances or dimensions of objects.
What is end correction in meter bridge?
End correction in a meter bridge refers to the added resistance due to the non-zero dimensions of the connecting wires or strips at the ends of the bridge. This added resistance needs to be accounted for when using the meter bridge for precise measurements. Calculating the end correction helps ensure accurate results when determining unknown resistances.
What are the Limitation of meter bridge?
Some limitations of a meter bridge include: Limited accuracy due to human error in taking measurements. Restricted use in measuring resistance values that are too high or too low. Sensitivity to external factors like temperature and vibrations, which can affect the readings. Inherent resistance in the connecting wires can introduce errors in the measurements.
Why do you use a meter bridge for measurements rather than a voltmeter and ammeter?
A meter bridge is used in some cases for precise resistance measurements. It can be more accurate than using a voltmeter and ammeter because it eliminates errors from contact resistance and internal resistance of the instruments. This method allows for more accurate determination of resistance by comparing two resistance values directly.
What is the difference between multiple and submultiple in physics?
In physics, multiples refer to values that are greater than a specified quantity, while submultiples refer to values that are smaller than a specified quantity. For example, a kilometer is a multiple of a meter (1000 meters make a kilometer), while a centimeter is a submultiple of a meter (100 centimeters make a meter).

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.
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is the use of jockey in meter bridge?
In a meter bridge, the jockey is used to slide along the wire to make contact with the resistance wire and balance the bridge by finding the null point. This allows for accurate measurement of unknown resistance by comparing it with a known resistance.
Unit of length in physics?
The meter
Why do you use 1 m wire in meter bridge?
It's not necessary to use 1 m of wire. Any length can be used.
What is the function of a Carey foster bridge?
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.
What is the physics behind a truss bridge?
A truss bridge uses trusses as the load bearing element of the bridge. Using statics physics, a truss bridge applies Newtonian motion to ensure that the load bearing elements do not go out of a tension/compression equilibrium.
Why is meter bridge called so?
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.
