WebIn an n-p-n transistor, the current gain for common emitter configuration is 80. If the emitter current be 8.1 mA, then the base current will be WebSep 7, 2016 · For an NPN (silicon) transistor to turn ON the base needs to be at least 0.6V more positive than the emitter. For a (red) LED to turn ON you need at least 1V8 across it. …

WebThe npn transistor is made up of three semiconductor layers: one p-type semiconductor layer and two n-type semiconductor layers. The p-type semiconductor layer is sandwiched between two n-type semiconductor layers. The npn transistor has three terminals: emitter, base and collector. WebIn an NPN transistor the collector current is 24 mA. If 80% of electrons reach collector its base current in mA is A 36 B 26 C 16 D 6 Solution Given ic = 80 100×ie ⇒24 = 80 100×ie ⇒ … graphite polystyrene insulation
