A potentiometer is connected across `A `and `B` and a balance is obtained at `64.0 cm`. When the potentiometer lead at `B` is moved to `C`, a balance is found at `8.0 cm`. If the potentiometer is now connected across `B` and `C`, a balanced will be found at

A potentiometer is connected between A and B and the balance point is obtained at 203.6cm. When the end of the potentiometer connected to B is shifted to C, then the balance point is obtained at 24.6cm. If now the potentiometer be connected between B and C, the balance point will

When the balance point is obtained in the potentiometer, a current is drawn from?

In a potentiometer, balance point is obtained, when

For a cell of e.m.f. 2 V , a balance is obtained for 50 cm of the potentiometer wire. If the cell is shunted by a 2Omega resistor and the balance is obtained across 40 cm of the wire, then the internal resistance of the cell is

In a experiment for callibration of voltmeter a standard cell of emf 1.5 V is balanced at 300 cm length of potentiometer wire. The P.D across a resistance in the circuit is balanced at 1.25 m. If a voltmeter is connected across the same resistance it reads 0.65 V. The error in the volt meter is

There is a potentiometer wire of length 1200 cm and 60 mA current is flowing in it. A battery of emf 5V and internal resistance of 20 ohm is balanced on potentiometer wire with balancing length 1000 cm. if a voltmeter is connected across the cell, the balancing length decreasing by 20 cm find reading of the voltmeter
