The balancing length on a potentiometer wire with a cell of emf `2V` and internal resistance `1Omega` connected in the secondary circuit with no load is `200cm`. If a resistor of `19Omega` is connected parallel to the cell, the balancing length

A cell of emf E and internal resistance r connected in the secondary gets balanced against length l of potentiometer wire. If a resistance R is connected in parallel with the cell, then the new balancing length for the cell will be

A cell of emf 'E' and internal resistance r connected in the secondary gets balanced against length l of potentiometer wire. If a resistance 'R' is connected in parallel with the cell, then the new balancing length for the cell will be

The balancing length of a potentiometer wire is 220cm when a cell of emf 1.1v is used in the secondary circuit.If it is replaced by a cell of emf 2.5v the balancing length becomes

4 cells each of emf 2 V and internal resistance of 1Omega are connected in parallel to a load resistor of 2Omega . Then the current through the load resistor is

A cell of emf (E) and internal resistance (r) is balanced across (l) length of potentiometer wire. If another cell of emf 2E and internal resistance (2r) is connected in parallel to the first cell , then the balancing length will be

The balancing length for a cell is 560 cm in a potentiometer experiment. When an external resistance of 10 Omega is connected in parallel to the cell , the balancing length changes by 60 cm. If the internal resistance of the cell is (n)/(10) Omega the value of n is ....

In a potentiometer experiment . A cell produces balance in the wire at 240 cm. balancing length change to 120 cm when a resistance 2Omega Is connected parallel to the cell. Find out the internal resistance of the cell.

3V poteniometer used for the determination of internal resistance of a 2.4V cell. The balanced point of the cell in open circuit is 75.8cm. When a resistor of 10.2Omega is used in the external circuit of the cell the balance point shifts to 68.3cm length of the potentiometer wire. The internal resistance of the cell is
