Define - terminal voltage of the cell? What is the e.m.f of a cell?

Where does the emf of a cell exist?

Under what condition will be terminal petential difference be more than the e.m.f. of a cell?

Under what condition will the terminal potential difference be more than the emf of a cell?

Define a unit cell

A cell of emf E and internal resistance r is connected across a variable resistor R. Plot a graph showing variation terminal voltage V of the of the cell Versus the current I. Using the plot,show how the emf of the cell and its internal resistance can be determined.

The emf values of the cell reactions Fe^(3+)+e^(-)rarr Fe^(2+) and Ce^(2+)rarr Ce^(3+)+e^(-) are 0.61 V and -0.85V respectively. Construct the cell such that the free energy change of the cell is negative. Calculate the emf of the cell.

Define fuel cell.

Define cell wall.

A cell of emf E and internal resistance r is connected to a variable external resistor R. the graph which gives the terminal voltage of cell V with respect to R is

A closed circuit consists of n cells connected in series. Each cell has an emf e and internal resistance r. The resistance of the connecting wires is assumed to be zero. What will be the reading of voltmeter connected to the terminals of one of the cells? It is assumed that the voltmeter has an infinitely high resistance as usual. Can it be real in practice?
