WebOct 8, 2015 · Now your assumption about the emitter being connected to a P region, the base to a N region and the collector to a P region is correct. And keep in mind that a Si atom has 4 valence electrons and that hole concentration will be in the order: emitter > collector > base and reverse for electron concentration.The calculations are quite easy to do. WebApr 15, 2011 · Nowadays I would use a suitable low R D S o n MOSFET for the switch. There are two way of bringing transistor in saturation mode: 1)Use of Rc resistor: we can calculate max current (Ic) by assuming Vce = 0. Ic (max)= Vcc/Rc. you can find corresponding base current (Ib) = Ic/ (beta).
