The symbol for an operational amplifier (op-amp) is represented as a triangle due to its three critical connections: two inputs and one output. This triangular shape effectively conveys the directional flow of signals, with inputs directed toward the output. The choice of this symbol is largely arbitrary, as it was established by convention and has been widely adopted in electronic schematics. Understanding this symbolism is essential for interpreting circuit diagrams accurately.
