If a BJT's base-emitter voltage is increased from 0.2V to 0.7V, describe the change in current flow in the junction.
💡 Hint: Recall how voltage and current are related in a diode.
A BJT is operating at a temperature of 60°C and the intrinsic carrier concentration doubles. How does this impact the minority carrier concentration?
💡 Hint: Think about the impact of temperature on carrier dynamics.
