In this video we take a most basic look at what is meant by cutoff, linear, and saturation, and why we use resistors on every leg of a BJT transistor. This is called biasing and can be as simple limiting the current at the collector, to as complex as setting up a voltage divider to hold the base in center of the linear region. No math, no formulas...just why.
