so i read about Parallel circuits and how they have the property of sharing energy and 1 battery powering lots of leds instad of a series one.but i dont get it to work, but i read also osmething about resistors and all that but i dont get it. for example, i want to connect 15 white LEDs of 3v (thats the seller told me) with about let say a 5-6v battery. how would it be in parallel?

thx and i also wanted to ask, i made a dynamo that create 5v of energy but not constant, its the one we shake, left right left right not the one that spins. it produces energy for aobut 1 second, but will it power those 15 LEDs in paralel?
also is it nessesary the resistors?

5v is 5v so yes that should be fine.

You need the resistors if you don't want your LEDs to burn out.
