Extra current

Why does the extra currebt draw of the  led in the lowe circuit kill the leds after it? Is it because the led basically is controlling how much current is going through the rest of bv the leds? Or is it merely the fact that when it turns on  the rest of the leds in parallel are now getting the nearly 5 volts when they only need about 2 volts?

By increasing the Current setting on the LED you decrease the resistance letting more current through, which could be too much for the next LEDs. Check the settings on the top left LED vs the bottom left one.

Hmm I thought voltafe decreased resistance?

I thought that leds afterthe one that used alot of current would just use the current they needed. Is it a si mk

Is it a simulation issue?

Oh I think I understand.. because the led is in series with the battery its basically setting up how much current will be going through the bv system. Like if it draws 20a the rest of bv the leds will have 20a passing through them?

In real life though would the resistance decrease? Or is this just how the simulation does things?

it is not a simulation issue
