Deduce the condition for obtaining maximum current through an external resistance, when the cells are mixed grouped.

Obtain the condition for maximum current through a resistor, when a number of cells are connected in parallel.

Obtain the condition fo rmaximum current through a resisitor, when a number of cells are connected in series.

To draw maximum current from a combination of cells, how should the cells be grouped?

Two cells of emf 2V and 4V and internal resistance 1Omega and 2Omega respectively are connected in parallel so as to send the current in the same direction through an external resistance of 10Omega. Find the potential difference across 10Omega resistor.
