current drawn by led increase with more leds you put which i saw in a video about thyristor ,but more leds means more resistance which means lesser current which is not true as per the video(https://youtu.be/4N1uLth1o9o )1:50-2:00that does not fall true how and why. PS -the channel is GreatScott's so its reliable
The LEDs he is using have an internal resistor or constant-current chip (there are no external series resistors as is normal).
When you connect them in parallel across a fixed voltage, each will draw a certain amount of current (depending on the LED and the voltage). Put 5 similar ones in parallel and you get about 5x the current that you get with one.
Current drawn by led increase with more leds you put which i saw in a video about thyristor.
The LEDs in the video were connected in parallel.
They are now acting like 4 times the original load (Single LED). The intention in the video is to simply I increase the load is about Thyristor latching.
The LEDs are also turned on without a current limiting element. It is not a good idea. The supply voltage there is just 2.7 V right about the forward voltage drop plus the additional drop in thyristor.
But more LEDs means more resistance
Hypothetically, yes if you connect them in series (considering the leads resistance in m ohms). Same way when you connect in parallel, it will be lesser than single LED one. But the change will be of no use to consider.
Connecting more LEDs in the video is like turning on more bulbs in the house. The current will have to increase.
