Emitter follower

Clean black textbook-style schematic of a single NPN bipolar junction transistor in emitter-follower (common-collector) configuration. Show the standard NPN transistor symbol with the emitter arrow pointing outward. The base terminal at the side, typically left, is the input node. The collector at the top is tied directly to the supply or common reference as the common terminal. The emitter is the output node, drawn on the lower or lower-right lead, with the output clearly taken directly from the emitter so it visually follows the input. Include a simple emitter load or bias path below the emitter, such as an emitter resistor to ground or a lower reference. Use compact, minimal black line-art circuit notation with clear transistor orientation and neat textbook proportions.
