Distinguish between emf and terminal potential difference of a cell.

Distinguish between Dry and wet cells

If internal resistance of a cell is proportional to current drawn from the cell. Then the best representation of terminal potential difference of a cell with current drawn from cell will be

A student measures the terminal potential difference (V) of a cell (of emf epsilon and internal resistance r ) as a function of the current (I) flowing through it. The slope and intercept of the graph between V and I , then respectively, equal

Distinguish between Kinetic energy and potential energy

Give the difference between e.m.f. and potential difference.

A car battery of emf 12V and internal resistance 0.05 omega receives a current of 60 A from an external source, then the terminal potential difference of the battery is

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

Assertion: Terminal potential difference of a cell is always less than its emf. Reason: Potential drop on internal resistance of cell increases terminal potential difference.

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

A cell of emf E and internal resistance r is connected in series with an external resistance nr. Than what will be the ratio of the terminal potential difference to emf, if n=9.
