State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
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.
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.
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.
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.
What are the application of Wheatstone bridge?
to measure the unknown resistance
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
How the resistance is measure?
Using an ohmmeter, Wheatstone bridge, etc.
How can you measure the resistance of field coil?
kelvin double bridge
What is the applications of kelvins double bridge?
to measure unknown resistance
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.
