Question 1
Analyze the effect on collector current if the base-emitter voltage is doubled while keeping the base-collector voltage constant.
💡 Hint: Use the exponential relationship of the current with respect to voltage.
Question 2
If a BJT operates in active mode with a high base-emitter voltage and a lower base-collector voltage, describe the impact on the overall gain (β).
💡 Hint: Consider how the biasing conditions affect the flow of charge carriers.
