Did you know some electronic components, like resistors, have a "preferred value" system due to their manufacturing process? It's known as the E-series, deriving from geometric progression. E12, for example, divides each decade of resistance into 12 values. This ensures that when stacked in a series, each component can couple with the next without significant value gaps, optimizing inventory and cost. Isn't electronics fascinating with its hidden harmonies? Share your own electronics insight or let's discuss more surprising facts!
