Transistor base Resistor CalculatorCalculator Vbe Vce hFE First you must check the datasheet of the transistor in question and identify the values Vbe, Vce, and hFE. These values are responsible for enabling transistor saturation. Here the example numbers shown are for the BJT BC548. RL Vcc Vi The load resistance RL is indicated in ohms, the supply voltage input is indicated as Vcc, and the input trigger voltage is indicated as Vi. Rb:
Swag saysVce is the saturation voltage (minimum).for BC547 you have to only consider the hFe and the RL, rest all can be as it isReply
What means NAN
not a number
https://en.wikipedia.org/wiki/NaN
Pls I want to begin with wireless circuits
Vce if bc548 is very low
If the transistor is bc547 what should be base resistor
Vce is the saturation voltage (minimum).
for BC547 you have to only consider the hFe and the RL, rest all can be as it is
