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.
Explain the advantages of the wheatstone bridge method of measuring resistance?
The biggest advantage of the Wheatstone bridge is the accuracy of the resistance readings. I had two cables short out underground, by knowing the resistance of the wires per foot I located the fault within 3 feet of where the two wires touched each other.
What kind of electrolyte used in salt bridge and why?
Kcl because of its high conductivity
Types of electrical circuit?
Series and parallelImproved AnswerThere are four categories of circuit: series, parallel, series-parallel, and complex. 'Complex' is a 'catch-all', used to describe circuits that are not series, parallel, or series-parallel. An example of a 'complex' circuit is a Wheatstone Bridge circuit.
What is the effect of inductive load on a single phase full wave bridge rectifier?
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
Which is used to measure a very small resistance of wires.?
To accurately measure very small resistances, you could use a Wheatstone Bridge.
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.
What is a Kelvin bridge?
A Kelvin bridge is a type of electrical circuit used for measuring very low resistances precisely. It minimizes errors caused by the resistance of the connecting leads by using a Wheatstone bridge configuration with additional connections to compensate for lead resistances. This allows for accurate measurement of small resistances in applications such as precision electronics and material testing.
Does post office box work on the principle of wheatstone bridge?
No, a post office box does not work on the principle of a Wheatstone bridge. A post office box is a secured physical container used for receiving mail, while a Wheatstone bridge is an electrical circuit used to measure unknown resistances by balancing two legs of a bridge circuit. The two concepts operate in entirely different domains—postal services and electrical engineering, respectively.
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.
What is the wheat stone bridge principle?
It is an circuit that is used to find the value of the resistances. The main principle behind it is the balancing an circuit by means of varying an resistance on connected to an arm of the circuit.When the resistance become equal to the variable resistance no current flows thus we can find the value of the 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.
How can the Murray loop test be used for locating the phase to phase fault?
By using wheatstone bridge principle we can proceed to find the phase to phase fault's.i:e the wheatstone bridge is mainly used to find the resistances/inductance/capacitances.it is mainly consists of 4 resistances like this(<>)& having a galvanometer in centre&a battery is connected to it. when ever the current flowing through the galvanometer is zero by varying the one resistance,then the ratio of two resistances connected at one end is equal to other two resistances ratio.By using the same principle ,one phase is connected to known resistance and a good cable is shorted to the fault cable.and other resistane is connected to the good cable&a galvanometer is connected to it.by varying the resistances the galvanometer shows null reading.then bridge is balanced & by using bridge equation we can solve to find the distance where the error is located
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 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.
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.
What is a Wheatstone?
