Challenge Problems
Push your limits with challenges.
Question 1
A transistor has an I_S of 50nA, and the base-emitter voltage is 0.75V. Calculate the base current I_B at room temperature (T=25°C).
💡 Hint: Remember, use the thermal voltage of 25mV.
Question 2
In a linear circuit, if the collector-emitter voltage is observed to swing between 2V and 8V with corresponding collector currents of 10mA and 20mA, determine the slope of the load line.
💡 Hint: Look for the change in current over the change in voltage.
