Question 1.
What is the typical forward voltage drop across a silicon diode?
Show hintHide hint
Think about what voltage allows current to flow in a silicon diode.
Question 2.
Name the two states of a diode and briefly describe each.
Show hintHide hint
Consider what happens when a diode is forward or reverse biased.
3Question 3.
What is the typical voltage drop across a silicon diode in the 'on' state?
- 0.2V
- 0.6V
- 1.2V
Show hintHide hint
Focus on the standard voltage values for silicon diodes.
4Question 4.
True or False: In the 'off' state of a diode, it behaves like a low resistance.
- True
- False
Show hintHide hint
Consider the definition of diode states.
Question 5.
A circuit consists of a silicon diode and a resistor of 15 kΩ. If the diode voltage drop is approximated to 0.7V, calculate the expected current through the diode.
Show hintHide hint
Remember to apply the voltage drop across the resistor.
Question 6.
In a piecewise linear model of a diode, derive the expressions for both the 'on' and 'off' conditions. How do they impact the analysis?
Show hintHide hint
Consider how you relate current to voltage in both models.
