Understanding Diodes, Transistors, and Number Systems
Basics of Diodes
- A diode is a two-terminal electronic component that allows current to flow in one direction only. It is formed by a p-n junction, where p-type and n-type semiconductors are joined together.
- When a forward bias is applied to the diode (positive terminal to p-type and negative terminal to n-type), the junction barrier is reduced, allowing current to flow.
- When a reverse bias is applied (positive terminal to n-type and negative terminal to p-type), the junction barrier is increased, preventing

A dominant and recurring theme, also common in his poetry, is the confrontation between the individual and authority. The individual wields desire, love, and freedom as weapons but is ultimately defeated by authority. A majority of his leading ladies grapple with frustration.
