These videos talked about the basics of how electronics work. It started with OHMS Law which is how electrical currents can be measured by Voltage (V), Current (I) and Resistance (R). The equation for these are V = I*R I = v/r and r = v/i. Resistance in important to understand because that is what controls the flow of an electrical current. The resistance in the air is really high and copper has very little. There are many other materials that have different amount of resistance. Voltage is how much power is running. If there is to much voltage running to a sensor or a LED light it can brake it which is why it is important to understand resistance so you can control the current and voltage. Fixed resistors are necessary for proper electronic functions.
