3 cards from this section. Quick, good the night before a test.
What are the three regions of a transistor?
Think about the order in n-p-n and p-n-p.
What is the primary function of a transistor?
Remember, it's often used in circuits.
What is the primary function of a transistor?
Think about where transistors are typically used.
True or False: In n-p-n transistors, the collector current flows into the collector terminal.
Envisage the direction of current flow.
If a p-n-p transistor has a base-emitter voltage of 0.7V and the base-collector voltage of 5V, is it in active mode? Explain your reasoning.
Check the bias condition for both junctions.
Draw the I-V characteristic curve for an n-p-n transistor under various operating conditions and describe how the curve changes as the voltage increases.
Consider how the current reacts to changes in voltage at each region.
