The characteristics of a bipolar transistor are described in terms of current. At the transistor electrodes, the magnitudes of current are related by the equation- l E = l B + l c (1.15) The above equation indicates that there are two current amplification factors for the static (d.c.) currents and two for small changes in the currents The characteristic curves of a transistor provide the relationship between collector-emitter voltage and collector current for different values of the base current.
