Question 1.
What occurs when a diode is in forward bias and the threshold voltage is reached?
Show hintHide hint
Consider what happens when the gate opens.
Question 2.
Define leakage current in the context of reverse bias.
Show hintHide hint
Think about the minor flow allowing a trickle.
3Question 3.
In which bias condition does current flow significantly through a diode?
- Forward Bias
- Reverse Bias
- Both
- Neither
Show hintHide hint
Consider which side of the diode powers 'on' the flow.
4Question 4.
True or False: Reverse bias allows a significant current flow.
- True
- False
Show hintHide hint
Think about the gate closing.
Question 5.
An LED diode has a cut-in voltage of 1.8V and shows a reverse breakdown at 5V. Describe its I-V characteristics in relation to these values.
Show hintHide hint
Assess how the diode behaves at its limits.
Question 6.
Design a simple circuit with a diode, specifying the required forward and reverse voltages, and explain the importance of these specifications.
Show hintHide hint
Think about how diodes regulate voltage and current.
