3 cards from this section. Quick, good the night before a test.
What is the definition of forward bias in BJTs?
Think about which voltage needs to be applied to enable current flow.
Define the term collector current.
Consider where the current is coming from.
What happens in a forward biased BJT?
Think about the direction of voltage applied.
True or False: Reverse saturation current (I_S) is significant during forward bias.
Remember, it’s a characteristic of reverse conditions.
A BJT operates with a base current of 5 µA and β = 150. If the base-emitter voltage is 0.7V, calculate the collector current (I_C) and explain its significance in a circuit design application.
Focus on using β to calculate the output current from the input.
In a circuit designed for audio amplification using a BJT, consider the effects of varying the base resistance on collector current and explain how it affects the overall gain.
Consider the relationship between current and resistance in a circuit.
