What is the value of unknown resistance R, if galvonometer shows null delection in the given meter bridge shows null deflection in the given meter bridge set up?
Answer the following : (a) Why are the connections between the resistors in a meter bridge made of thick copper strips? (b) Why is it generally preferred to obtain the balance point in the middle of the meter bridge wire? ( c) Which material is used for the meter bridge wire and why?
From the given sets of quantum numbers, the one that is inconsistent with the theory is:
Why should the area of cross-section of the meter-bridge wire be uniform ? Explian
13.Which of the following draws no current from the voltage source being measured? a Meter bridge b.wheatstone bridge c.Potentio meter d.None of these "]
For determination of resistance of a coil, which of two methods is better Ohm's law method or meter bridge method ?
In the circuit shows in Fig. 6.20 , a meter bridge is in its balance state. The meter bridge wire has a resistance of 1 Omega cm^(-1) . Calculate the value of the unknow resistance X and the battery of negligible internal resistance.
