[" When an electric cell "],[" drives current through "],[" load resistance,its Back "],[" emf,"]

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?

A cell of emf E and internal resistance ® is connected across an external resistance, R. The cell shall drive maximum current through the external resistance R only if

A cell of emf E and internal resistance r drives a current of 5 Ampere through an extenal resistance of 8 ohm. The current drops to 4 Ampere when the external resistance is increased to 10.1 ohm. Find the emf E and the internal resistance r of the cell.

A cell of internal resistance r drivers current through an external resistance R. The power delivered by the to the external resistance will be maximum when:

Acell of internal resistance r drives a current through an external resistance R . The power delivered by the cell to the external resistance is maximum when

Current is sent from an electric cell of emf 30 V and of negligible internal resistance through a resistance of 200 Omega . When an ammeter is introduced into the circuit is given a reading of 147 mA. Determine the resistance of the ammeter and also the percentage error in the measurements of current.

5When a cell of emf E and internal resistance r, is connected to the ends of a resistance R, then current through resistance is I. If the same cell is connected to the ends of a resistance R/2 then the current would be-

A cell of e.m.f. 1.5 V and internal resistance 1Omega sends a current through wires of resistance 6Omega and 12Omega connected in parallel. Find the current through each wire.
