Base current is the current flowing into the base terminal of a bipolar junction transistor (BJT), which controls the larger currents flowing between the collector and emitter terminals. It is crucial for determining the transistor's operation mode, such as active, cutoff, or saturation, thereby influencing the amplification properties of the BJT.

A Bipolar Junction Transistor (BJT) is a semiconductor device that can amplify or switch electrical signals, utilizing both electron and hole charge carriers. It consists of three layers of doped semiconductor material, forming two pn-junctions, and operates in active, cutoff, or saturation modes depending on the input signals at its base, collector, and emitter terminals.
