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.
💡 Hint: 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.
💡 Hint: Consider the relationship between current and resistance in a circuit.
