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?
