Four identical cells of emf epsilon and internal resistance r are to be connected in series. Suppose, if one of the cell is connected wrongly, then the equivalent emf and effective internal resistance of the combination is

If n cells each of emf E and internal resistance rare connected in parallel, then the total emf and internal resistances will be

Find equivalent emf of four different cells which are connected in parallel. Their emf's and internal resistance are 1 volt, 1 Omega , 2 volt, 1 Omega,3 volt, 1Omega,4 volt, 2 Omega and their connection is given below .

Two cells of emfs 1.5 V and 2.0v having internal resistance 0.2 Sigma and 0.3 Sigma respectively are connected in parallel . Calculate the emf and internal resistance of the equivalent cell .

Two cells of emfs epsilon_(1)and epsilon_(2) and internal resistances r_(1)and r_(2) respectively are connected in parallel . Obtain expressions for the equivalent (i) resistance and , (ii) emf of the combination.

When two resistors of (600pm3) ohm and (300pm 6) ohm are connected in parallel, value of the equivalent resistance is

Five cells each of emf E and internal resistance r are connecte in series. Due to oversight one cell is connected wrongly . The equivalent emf and internal resistance of the combination is

Assertion : Two non-ideal batteries are connected in parallel with same polarities on same: side. The equivalent emf is smaller than either of the two emfs. Reason : Two non-ideal batteries are connected in parallel, the equivalent inter resistance is smaller than either of the two internal resistances.

In the series combination of n cells each cell having emf epsilon and internal resistance r. If three cells are wrongly connected, then total emf and internal resistance of this combination will be
