In a meter bridge experiment
In a meter bridge experiment, the null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. If X< Y, then where will the new position of the null point be from the same end, if one decides to balance a resistance of 4X against Y?

When an ammter of negligible internal resistance is inserted in series with circuit it reads 1A When the voltmeter of very large resistance is connected across X it reads 1V. When the point A and B are shorted by a conducting wire, the voltmeter meausres 10V across the battery. The internal resistance of the battery is equal to

A voltmeter having resistance of `1800 Omega` is employed to measure the potential difference across `200 Omega` resistance which is connected to DC power supply of 50 V and internal resistance `20 Omega`. What is the percentage change in potential difference across `200 Omega` resistance as a result of connecting voltmeter across it ?

Figure shows a circuit that may be used to compare the resistance R of an unknown resistor with a 100 Ω standard. The distance l from one end of the potentiometer slider wire to the balance point are 400 mm and 588 mm when X is connected to Y and Z, respectively. The length of the slide wire is 1.00 m. What is the value of resistance R?
