When a resistance of 12 Omega is conencted with a cell of emf 1.5 V,0.1 A current flows through the resistance internal resistance of the cell is

5 Identical cells are connected in series to form a row, 3 such rows are connected in parallel to form a combination of cells. The combination sends 1A current through an external resistance of 9 Omega . But if the resistance of the external circuit be 19 Omega then the currents is reduced to half of its previous value. Determine the em and internal resistance of each coil.

A cell supplies a current of 2 A when it is connected to a 5 Omega resistance and supplies a current of 1.2 A, if it is connected to a resistance of 9 Omega . Find the e.m.f and internal resistance of the cell.

A Cell sends a current of 0.5 A through a 2 Omega resistance. If the resistance is increased by 5 Omega , the current falls to 0.25 A. Find the emf of the cell and its internal resistance.

An electric cell is sending electric currents through a resistance of 10 Omega . IF a shunt of 1 Omega is connected with that resistance then the current through the 10 Omega resistance becomes half of the previous value.What is the resistance of the cell?IF the current through the shunt be 0.9A, then what will be the emf of the cell?

When a Laclanche cell is connected to a 10Omega resistance then a current of 0.25 ampere flows in the circuit. If the resistance is reduced to 4Omega then current becomes 0.5ampere. The internal resistance of galvanometer will be-
