LEDs - Light Emitting Diodes - Basic Introduction
This content starts by explaining that LEDs convert electrical energy into light energy, making them efficient devices that stay cool compared to other lamps. It then delves into the polarity of an LED, describing how to connect it in a circuit with proper positive and negative terminals. The content also explains the importance of using a current limiting resistor in series with the LED to prevent damage from excessive current flow. Furthermore, it provides insight into the electrical symbol of an LED, highlighting its difference from a regular diode by featuring two arrows emanating from it, indicating the positive terminal on one side and the negative terminal on the other. The content also covers conventional current direction in LEDs, stating that when current flows from the anode to the cathode, the LED is turned on if the voltage is sufficient. Additionally, it explains how LEDs allow current to flow in one direction but block it in the opposite direction, making them useful for electronic projects. When considering an LED for such a project, three key factors are emphasized: the forward voltage drop of the LED, which varies by color and is typically around 2.2 volts for green LEDs; the need to ensure sufficient voltage to turn on the LED; and the importance of using the correct polarity when connecting the LED in a circuit.

Lec 12 MIT 6.002 Circuits and Electronics, Spring 2007
The subject matter revolves around introducing storage elements in electronic systems. It discusses how traditional components like resistors, voltage sources, and logic gates (such as AND gates and inverters) have a specific property - their output at any given time is solely dependent on the input(s). This means that if you were to build a circuit using these components, the output would be a function of the inputs alone. However, with memory devices, the output depends not just on the current input but also on past states or background conditions. The content emphasizes how this introduces a new fundamental difference in electronic systems and what implications this has for understanding circuit behavior. It highlights how traditional analysis methods may no longer apply when dealing with memory-based components. The importance of considering past states becomes crucial, as demonstrated through an example using inverters to show the distinction between standard logic gates and memory devices.
