These exterior columns are called energy rails and are used to obtain and supply energy to the board. You can however join an LED to a 3V or smaller battery and not using a resistor. A normal LED generally needs a voltage of round 2V and a current of 20mA or .02A to function appropriately. In order to find out the resistor dimension, we have to use a formulation known as Ohm’s law as shown beneath. There are many forms of electronic symbols and so they differ slightly between nations. Below are a few of probably the most commonly used electronic symbols within the US.
