    The current amplification factor or current gain of a transistor is the ratio of output current to the input current. If the transistor is connected on base mode the current gain α=IE​IC​​ and if the transistor is connected in common emitter mode, the current gain α=IB​IC​​.

    The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, and its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958

    In the active region, collector-base Junction remains everse biased while base-emitter junction remains forward biased. Consequently, the transistor will function normally in this region.

    In statistics, quality assurance, and survey methodology, sampling is the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question.
