In this Experiment I had to make a circuit and use a transistor as a switch and run some tests on it using a multimeter.
This shows that the transistor has a knee voltage of .74 volts
Vce = 0.05v
There is only a voltage drop of 0.05v, this shows that the current is flowing through the transistor freely.
In this graph, in region A the transistor is in the "fully on" position and in region B it is in the "fully closed" posistion.
Power dissapating at a Vce of 3v,
Vce = 3 Ic = 14
Ic * Vce = Pd
14 * 3 = 42mW
Beta at at Vce of 2,3 & 4 volts
Vce2 = 20 / 0.8 = 25mA
Vce3 = 14 / 0.5 = 28mA
Vce4 = 5 / 0.2 = 25mA
