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.

What happens when unknown resistance is changed to other armin wheatstone bridge?
Changing the unknown resistance in a Wheatstone bridge will result in an imbalance in the circuit, causing a potential difference across the bridge. This potential difference can be used to determine the new value of the unknown resistance by adjusting other known resistances until the bridge is balanced again.
Why galvanometer is connected in wheatstone bridge?
A Wheatstone Bridge is used to measure resistance of an electrical / electronic component. The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter! It uses a completely-different method of measuring resistance and is significantly more accurate than a multimeter. The purpose of the very sensitive galvanometer is to detect when the Bridge circuit is 'balanced', by sensing the current (not voltage!) passing through it. When no current flows, the Bridge is balanced.
What is the difference between compression and tension and how does it affect your bridge?
Compression is pushing things together and tension is pulling things apart. A clothesline is under tension and a stack of firewood is under compression. How it affects the bridge depends on how well it is engineered. Properly built it'll hold up to its various loads w/o problems,
How is electric resistence measured?
Resistance is usually measured using an ohmmeter, however if very high precision is needed a wheatstone bridge is used.
What are the three different places on a bridge that would experience different forces?
The three different places on a bridge that would experience different forces are the supports (where vertical forces are highest), the center span (where compression and tension forces are highest), and the connections between bridge sections (where shear forces are highest).
What was Charles wheatstones connection to his inventions the bell telephone company?
The Wheatstone Bridge was a device used to locate trouble in cables.
How the resistance is measure?
Using an ohmmeter, Wheatstone bridge, etc.
Difference between flyover and overhead bridge?
Boxgirder bridge
What is the difference between a suspension bridge and a truss bridge?
giant cables and abutments
What is the difference between length and span of a bridge?
The span is the distance between supports. The sum of the span lengths is the bridge length.
What is the difference between The London Bridge and The Sydney Harbour Bridge?
There are no similarities between the two bridges. They are completely and totally different.
What is difference between piers and abutments in bridge?
AbutmentA retaining wall supporting the ends of a bridge or viaduct.Pierssupport if continuous bridge
What is the difference between the Carey foster bridge and meter bridge?
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
What is the difference between the Suspension bridge and the Beam bridge?
The different between suspension bridge and beam bridge are beam bridge are for short distance but suspension bridge for long distance. Beam bridge are used for highway passes and suspension bridge for wide waterway passes.
What is the difference between router and brouter?
A Bridge Router or brouter is a network device that works as a bridge and as a router
What is the difference between South Bridge and North Bridge?
The people from the South will have a slightly different accent. Y'all ;-)
Difference between bridge and repeater?
A bridge acts as "bridge" between two networks or network subnets. A repeater merely strengthens the signal. You can have a repeater that only acts on one wire.
