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 else can I help you with?
Are there any other methods for measuring resistance?
An Ohm Meter.
Difference between ac and dc bridge?
DC Bridge... We use DC supply, Detector is also a DC current detector and we use only resistive components no need for wegner's earthing device balancing time is comparatively less.. where as in AC bridges opposite of above. i.e. AC supply, AC current detector resisitive+ reactive componants need for wagner's earthing device and balancing time is high as we use AC supply..
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 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 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 a Wheatstone bridge used for?
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.
How do you measure end correction of a meter bridge?
The end correction of a meter bridge can be measured by comparing the balance point of a known standard wire to the balance point of an unknown wire on the meter bridge. The difference in lengths between the two balance points is equal to the end correction.
Difference between meter in and meter out in hydraulics?
"in" and "out" are the direction of the pressure.
What is the difference between running meter and linear meter?
None.
What material is used to make a wheatstone bridge?
A wheatsone bridge is an electrical circuit made from 4 resistors, 3 of a precisely known value and a 4th of unknown value which we want to measure. There is also a volt meter. See Wikipedia link for circuit diagram and more info.
What is the Difference between cubic square meter and loaded meter?
Hello
What are the difference between LCR meter and electrochemical impedance spectroscopy?
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
