A potentiometer wire of length L and resistance R is connected to a driver cell of negligible internal resistance and emf E. A cell of emf E/2 is balanced at a length L/2. If the length of the potentiometer wire is doubled, at what length will the same cell be balanced?

The emf of a battery '$A$' is balanced by a length of $80\,cm$ on a potentiometer wire. The emf of a

standard cell $1V$ is balanced by $50cm$. The emf of '$A$' is

A potentiometer wire has a uniform resistance per unit length. When a cell of emf E is connected, the balance length is l. If the length of the potentiometer wire is increased by 25% without changing the driving cell, the new balance length for the same cell E will be:

In a potentiometer experiment when a battery of emf $2V$ is included in the secondary circuit, the balance point is $500\,cm$. Find the balancing length of the same end when a cadmium cell of emf $1.018V$ is connected to the secondary circuit.

Which of the following factors does NOT affect the balancing length of a potentiometer?

A potentiometer wire of length L and resistance R is connected to a driver cell of negligible internal resistance and emf E. A cell of emf E/2 is balanced at a length L/2. If the length of the potentiometer wire is doubled, at what length will the same cell be balanced?

In a potentiometer experiment, the balancing length for a cell is found to be $l$. If the driver cell is replaced by another cell of double the emf, what will be the new balancing length, assuming all other parameters remain constant?

In a potentiometer experiment when a battery of emf $2V$ is included in the secondary circuit, the balance point is $500\,cm$. Find the balancing length of the same end when a cadmium cell of emf $1.018V$ is connected to the secondary circuit.

In a potentiometer experiment, the galvanometer shows no deflection when a cell is connected across $60\,\,cm$ of the potentiometer wire. If the cell is shunted by a resistance of $6\,\,{\rm{\Omega }}$, the balance is obtained across $50\,\,cm$ of the wire. The internal resistance of the cell is

The length of a potentiometer wire is $l$. A cell of emf E is balanced at a length $l/4$ from the positive end of the wire. If the length of the wire is increased by $l/2$, at what distance will the same cell give a balanced point? (Potentiometer battery is ideal)

A potentiometer is being used to compare two cells of emfs $E_1$ and $E_2$. The balancing lengths are found to be $l_1$ and $l_2$ respectively. If a resistance R is connected across $E_2$, its balancing length changes to $l_3$. Which of the following relations must hold true?
