Statement I: Voltmeter always gives emf of a cell if it is connected across the terminals of a cell.
Statement II: Terminal potential of a cell is given by `V= E - ir`.

What do a voltmeter connected to two terminals of a cell read: the emf or the terminal potential difference?

The potential difference between the terminals of a cell in open circuit is 2.2 V. With resistance of 5 Omega across the terminals of a cell, the terminal potential difference is 1.8 V. The internal resistance of the cell is

What is the relationship between potential difference across the terminals of a cell and emf of the cell ?

What is the relationship between potential difference across the terminals of a cell and emf of the cell ?

The potential difference betwee11 the terminals of a cell in an open circuit is 2.2 V. When a resistor of 5 Omega is connected across the terminals of the cell, the potential difference between the terminals of the cell is found to be 1.8 V. The internal resistance of the cell is

Can the terminal potential difference of a cell exceed its e.m.f. ?

Distinguish between emf and terminal potential difference of a cell.
