Challenge Problems

Push your limits with challenges.

Question 1

A silicon diode in a circuit has an input voltage of 5V and a resistor of 1kΩ while the diode’s cut-in voltage is 0.7V. Calculate the output voltage if the reverse saturation current is negligible.

💡 Hint: Use the diode behavior above threshold.

Question 2

When an AC signal of 1V peak is superimposed on a 5V DC on the diode circuit, how does the AC signal affect the output voltage? What happens if the DC is reduced?

💡 Hint: Consider what happens when the DC level is below the cut-in voltage.
