Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Considering a silicon diode with a threshold voltage of 0.7 V, calculate the current when 1 V is applied, assuming the reverse saturation current Is is 1 mA and n = 1. The temperature is room temperature (approximately 300 K).

💡 Hint: Calculate using constants and simplify.

Challenge 2 Hard

Design a simple half-wave rectifier circuit using a silicon diode and explain how forward bias behavior contributes to its function.

💡 Hint: Draw the circuit and label the flow of current.
