Let's consider in great detail how to connect any LED to any battery, power bank, batteries, power supply. The video consists of five parts. This first part considers the main parameters of any battery, power bank, batteries, power supply, as well as the main parameters of any light-emitting diode, also called LED. The main parameter of the former is voltage, which is measured in volts by connecting a voltmeter in parallel to a power source or load. Among the many parameters of LEDs, we are interested in two of the most important ones - direct current and direct voltage drop. Current is measured in amperes in series in an electrical circuit with a load. This first part shows the simplest case - how to connect any LED to any battery, power bank, batteries, provided that the voltage of the power source and the direct voltage drop on the LED are equal. 1.
