Common emitter amplifier basic grounded emitter

Simplified textbook schematic of a single-stage NPN bipolar junction transistor in common-emitter configuration, drawn as clean black circuit-symbol line art on a white background. The transistor is shown in a classic vertical layout with base on the left as the input, collector at the top or upper right as the output node, and emitter at the bottom tied directly to the common reference or ground. A collector load resistor connects from the collector upward to the positive supply rail. The output is taken from the collector, and the stage may include simple labels such as B, C, and E or input/output markings.
