Key Concepts

Electromotive Force (emf)

Electromotive force (emf) is the measure of energy provided by a cell per unit charge as it moves from the negative to the positive terminal. It is a fundamental parameter in determining the voltage supplied by a battery or cell in any circuit configuration.

Voltage and Current Relationships in Circuit Configurations

The arrangement of cells in a circuit—either through series or parallel connections—directly influences the distribution of voltage and current. Series arrangements add individual emfs to increase the total voltage while maintaining the same current, whereas parallel arrangements keep the voltage unchanged but increase the current capacity by summing the contributions from each cell.

Series Combination of Cells

In a series combination, the cells are connected end-to-end, so that the total voltage is the sum of the individual cell emfs. This configuration is primarily used when there is a need to obtain a higher voltage than what a single cell can provide, though the available current remains the same as that of a single cell.

Parallel Combination of Cells

In a parallel combination, the cells are connected such that all their positive terminals are linked together and all negative terminals are linked together. This configuration supplies the same voltage as one individual cell while providing a greater current capacity because the individual currents contributed by each cell are combined.
