3 cards from this section. Quick, good the night before a test.
Define what biasing means in the context of transistors.
Think about the voltage necessary to set up active operation.
Name the two main types of bipolar junction transistors.
Consider their charge carriers.
What junctions need to be forward-biased in an n-p-n transistor?
Think about which junction allows connections to the emitter directly.
True or False: In a p-n-p transistor, the collector current is the same direction as the emitter current.
Recall the direction of current in terms of charge carriers.
Design a circuit using a p-n-p transistor that requires a specific collector current of 5mA, given a base current of 50µA. Ensure to calculate the appropriate β needed.
Use the formula relating I_C to I_B.
If an n-p-n transistor operates with a collector voltage of 12V and a collector current of 3mA, what is the power delivered to it, assuming the base-emitter voltage remains constant at 0.7V?
Power is calculated using the voltage across and the current through a device.
