4 cards from this section. Quick, good the night before a test.
What type of materials are used in an n-p-n transistor?
Think about the order of layers in the transistor.
What is the meaning of forward bias in a transistor?
Consider the implications for both the base-emitter junction.
What is a key difference between an n-p-n and a p-n-p transistor?
Think about the arrangement of materials.
True or False: In a p-n-p transistor, the emitter must be at a lower potential than the base.
Recall the requirements for forward bias.
Analyze a given n-p-n transistor circuit where the base-emitter voltage is set at 0.7V and the collector-emitter voltage at 5V. Calculate the expected collector current if β = 150.
Remember to establish the base current using the supply voltage and the base resistor.
Given a p-n-p transistor with an emitter current of 2mA, calculate the base and collector currents if β is known to be 100. Discuss what happens if the base-emitter voltage is lowered.
Relate the changes in base current to the effects on collector current.
