WebMar 3, 2007 · In a BJT, the base is connected to the emitter via an internal resistance. The resistance is in the low ohms. Therefore, there is a means for current flow. Hence, the BJT is a current-controlled device. Specifically, the current through the device (collector to emitter -- assuming an NPN) is a function of the current into the base. WebJun 11, 2015 · A BJT is saturated when both junctions are forward-biased. The V C E ( S A T) is a nominal value that depends on the collector current and such. V C E cannot be lower than V C E ( S A T), by definition. Whatever V C E value is measured at saturation is V C E ( S A T) (for the given additional conditions that are present). – Kaz WebMar 13, 2024 · The BJT varies its output current (defined here as the current flowing through the device from emitter to collector or vice versa) according to its base drive current multiplied by its current gain (h FE). Because of this, the BJT is often described as a current-controlled device. how to show total in datagridview footer c#
