3 cards from this section. Quick, good the night before a test.
What is the primary function of biasing in a transistor?
Think about what conditions are needed for transistors to work effectively.
In n-p-n transistors, which junction is forward biased?
Consider the flow of current when the transistor is activated.
What is the primary requirement for a p-n-p transistor to operate in its active region?
Recall the biasing conditions for p-n-p transistors.
In an n-p-n transistor, which current enters the device?
Think about the directions of flow for the different currents in a n-p-n.
You have an n-p-n transistor with the following parameters: base current of 20 µA and a current gain (β) of 150. Calculate the collector current.
Make sure to understand the relationship between I_C and I_B using the current gain.
For a p-n-p transistor with a collector current of 2 mA and a β of 50, what would be the required base current?
Try reusing the formula we've discussed in class regarding current relationships.
