Challenge Problems
Push your limits with challenges.
Question 1
You have a circuit with a silicon diode and a resistor where the input voltage is 5V. If the cut-in voltage is 0.7V and the resistor is 1k ohm, calculate the output voltage.
💡 Hint: Use the concept of Ohm’s law for calculating the voltage drop across the resistor.
Question 2
Design a basic rectifier circuit using a diode and explain how it converts AC to DC, including describing the output signal shape.
💡 Hint: Visualize how diodes only allow positive voltages to pass through.
