The scene is an indoor educational setting, a classroom in Okigwe, Nigeria. An adult female, with dark braided hair and wearing a dark patterned long-sleeved top, stands at the front, facing a whiteboard mounted on a yellow wall. The whiteboard displays handwritten electrical engineering diagrams and text, specifically a "Common Base (CB) amplifier" circuit, NPN and PNP transistor symbols, input/output waveforms, and formulas for "Voltage Gain" and "Input Resistance." In the foreground, at least three individuals, visible from the back of their heads and shoulders, are seated, wearing white collared shirts, and observing the presenter and the whiteboard.
