Connect the multimeter between the base and emitter.
Note the voltage reading and explain what this reading is indicating.
: 0.730V, this indicates a saturated transistor that is fully on.
Connect the multimeter between collector and emitter.
Note the voltage reading and explain what this reading is indicating.
: 50mV, this indicates again a saturated transistor as Vce will be very close to 0V when fully on.
A = Saturated (fully on)
B= Cut-Off (fully off)
How does a transistor work in these regions? Explain in detail:
When fully Saturated Vce will be very small but be putting out a high current.
When fully Cut-Off Vce will be small or large but be putting out very small current because the transistor becomes reverse biased.
What is the power dissipated by the transistor at Vce of 3V?
: Pd = Vce x Ic
3V x 12.5mA
37.5V Correction: 37.5W
What is the Beta of this transistor at Vce 2, 3, & 4 volts?
: B = Ib / Ic
2V: 20mA / 0.8mA = 25
3V: 12.5mA / 0.5mA = 25
4V: 5mA / 0.2mA = 25
This is because the beta will always be the same as it is taken off the gradient line you see in the graph.
