Final Answer:
The emf of the battery, formed by connecting eight identical cells in series and then paralleling six such rows, is 16 volts, reflecting the cumulative emf of the individual cells in series arrangement.
Explanation:
The emf of the battery, resulting from the arrangement of eight identical cells in series and their subsequent grouping in six parallel rows, remains unswervingly set at 16 volts. This constancy in the battery's emf is a product of the cumulative effects of both series and parallel connections.
Initially, when the eight cells are aligned in series, each possessing an emf of 2V, their individual emfs harmoniously add up. Consequently, the series arrangement produces a total emf of 16V (8 cells × 2V/cell). When these rows are later combined in parallel, the emfs of the individual cells and thus the overall emf persist unaffected.
It's crucial to recognize that while internal resistance can certainly influence the total circuit resistance and subsequent current flow, its presence does not tamper with the fundamental emf value of the battery. Emf is a reflection of the energy conferred to each unit of charge traversing the circuit, serving as the driving force for current flow, regardless of any internal resistance effects.
The unchanging emf value at 16 volts resonates as a steadfast constant in diverse applications. From powering everyday electronics to energizing intricate systems, the reliability of this energy parameter is paramount for sustaining consistent operations.
In essence, the maintenance of the battery's emf at 16 volts emanates from the amalgamation of individual cell emfs within the series arrangement, exemplifying the enduring nature of this essential energy characteristic.
