The video tutorial on Engineering Education explains how to find the output voltage (Vout) at the collector of a BJT in a common emitter configuration. The problem is introduced with given parameters: VBE, transconductance, and output resistance. The instructor guides viewers to use a reference handbook to understand the low-frequency small signal equivalent circuit of the BJT. The circuit is drawn and analyzed, focusing on the dependent current source and output resistor. The calculation of Vout is demonstrated step-by-step, resulting in a final value of 4 volts. The video concludes with a call for viewer interaction.
