Biasing of the transistor means setting up a fixed level of current which should flow on the transistor with fixed level of the voltage drop across the transistor. For proper working of the transistor, the base emitter junction is forward biased. By making the base-emitter junction for word biased the resistance of the base-emitter become very low as confased loith the resistance of collector-base junction and reverse biase junction of collector base junction's resistance is high
