    Amplification is the process of linearly increasing the amplitude of an electrical signal. A transistor can act as an amplifier directly using the gain, b. When a transistor is biased in the active (linear) region, the BE junction has a low resistance due to forward bias and the BC junction has a high resistance due to reverse bias.
