A secondary cell after long use has an emf of 1.8 volt and a large internal resistance of 380 ohm. What maximum current can be drawn from the cell? Can it drive the starter-motor of a car?

To the parallel combination of two resistances 3 Omega and 1 Omega , a series combination of resistances 2.15 Omega and 1 Omega and a battery are connected. The interval resistance of the battery is 0.1 Omega and the emf is 2V. Determine the values of current flowing through the resistances. Draw the diagram of the circuit.

Two separate circuits are made with resistances r_(1)andr_(2) connected to the same storge battery . What should be the interal resistance (r) of the storage battery for which an equal amount of heat is produced in the exteranal circuits ?

An infinite ladder network of resistances is constituted with 1Omega and 2Omega resistances as shown. The 6v battery between A and B has negligible internal resistance. What is the current that passes through the 2Omega resistance nearest to the battery?

A resistance of 12 Omega is connected with a battery of emf 1.5volt to have 0.1A current. What is the intemal resistahce of the battery?

Three resistances of 4 Omega , 5Omega and 12 Omega are connected in parallel.A battery of emf 10 v and internal resistance 0.5 Omega . Is connected with that combination .Find out the currents through this battery and through each of this three resistances.

The steady state current in a 2Omega resistor shown in fig will be - (The internal resistance of the battery is negllgible and the capacitance of the capacitor C is 0.2muF )

36 cells each of internal resistance 0.5 Omega and emf 1.5 V each are used to send current through an external circuit of 2 Omega resistance. Find the best mode of grouping then for maximum current and the current through the external circuit.
