Why Kelvin bridge is more suitable for measurement of low resistance give reason?
7. Why Kelvin bridge is used for measurement of low resistance? Explanation: While measuring very low resistances the contact and lead resistances cause significant errors in the value of the measured resistance. As a result Kelvin bridge is used for measurement of low resistances.
Which bridge is suitable for low resistance?
The Kelvin Bridge is a variation of the Wheatstone bridge which enables low resistances to be measured.
Which method is best suited for precise measurement of low resistance?
Which is the most popular method for measuring low resistance? Explanation: Kelvin’s double bridge is used for the measurement of low resistances of the order of 1ῼ or less. Ammeter voltmeter method is used for the measurement of current flowing through and the voltage across the circuit.
Why the Kelvin Bridge is known as a double bridge?
Why it is called double bridge? It is because it incorporates the second set of ratio arms as shown below: In this the ratio arms p and q are used to connect the galvanometer at the correct point between j and k to remove the effect of connecting lead of electrical resistance t.
Why can’t a Kelvin bridge be used for the measurement of low quality factor value Mcq?
Explanation: A Kelvin bridge can be used for the measurement of high Quality factor values. Due to bridge imbalance problem, Kelvin bridge can’t be used for measuring low Quality factor values.
Which of the following method will suitable for measurement of resistance of ammeter shunt?
The shunt-type ohmmeter is used for measuring low values of resistance. It operates on the same basic principle as an ammeter shunt.
Why Kelvin Bridge is called Double Bridge?
Definition: A kelvin bridge or kelvin double bridge is a modified version of the Wheatstone bridge, which can measure resistance values in the range between 1 to 0.00001 ohms with high accuracy. It is named because it uses another set of ratio arms and a galvanometer to measure the unknown resistance value.
