Cells in Series and in Parallel

The video tutorial explains how cells, like resistors, can be combined in electric circuits. It covers the series and parallel combinations of cells, detailing how to calculate equivalent EMF and internal resistance. The series combination involves summing individual EMFs and resistances, while the parallel combination requires more complex calculations involving currents and potential differences. The tutorial provides equations for both combinations and discusses how these principles can be extended to multiple cells.

What is the equivalent cell when combining two cells of EMFs E1 and E2 in series?

How can the potential difference between the terminals A and C be expressed in terms of E1, E2, and the internal resistances?

What is the rule for the equivalent EMF of a series combination of N cells?

Describe how the equivalent internal resistance of a series combination of N cells is calculated.

In a parallel combination of cells, how is the current related to the potentials at the terminals?

What equations can be derived for the potentials in a parallel circuit with two cells?

How can the equations for multiple cells in parallel be generalized?
