In a metre bridge experiment, resistances are connected as shown in the figure. The balancing length 11 is 55 cm. Now, an unknown resistance x is connected in series with P and the new balancing length is found to be 75 cm. The value of x is:

write objective for the lab report of to determine of the end correction of a meter bridge in points

In a Wheatstone's bridge all the four arms have equal resistance R. If the resistance of the galvanometer arm is also R, the equivalent resistance of the combination as seen by the battery is

Two resistance are given as R1=(10±0.5) Ω and R2=(15±0.5) Ω. The percentage error in the measurement of equivalent resistance when they are connected in parallel is

Statement 1In1In a Meter Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance.and Statement 2 Resistance of a metal increase with increase in temperature.JEE Advanced 2008 (Paper 1)AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.CStatement 1 is true, Statement 2 is false.DStatement 1 is false, Statement 2 is true
