Led can tolerate any amount of current

Nettet27. feb. 2012 · LED manufacturers carefully document the amount of current required for a given light output, so it’s not hard to decide what current to provide. The voltage needed to maintain that current level might vary from, say, 3 to 3.6 volts. NettetIf each LED requires 1.5 V (that sounds low unless they are red), and you have 16-20 of them in series, then the total string will require 1.5V*16 = 24V to 1.5V*20 = 30V to light. So no, a 12 volt battery isn't going to do anything useful. Second, there is no such thing as amount of electricity.

The reason why a power-line has … NettetIn electronics, polarity indicates whether a circuit component is symmetric or not. LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work.

For example, … NettetThey will tolerate it so much that they won't even get started. 16 x 1.5V is 24V, anything less and the LEDs won't light. What you should do is to split your long string of 16 LEDs into several parallel strings. 8 x 1.5V is 12V, so it may look like we're there. Not. You need some headroom to control the current. That's indeed the resistor.
