Resistors lower current, not voltage. [...] voltage isn't the same as current
Hi soeren, which values would i multiply? and how come the digimeter still shows that there is 5v? thanks.
hi sorry to confuse you with my question,
[...] after that you had mensioned that it also lowers voltage (the resister) i am just interested in understanding exactly what is going on for furthur reference, [...] now i'd assume the resister would take the voltage down to a lower voltage for the LED requirement, however using the digi meter this is not the case it still shows me 5v, this is what i am trying to understand.... hence i asked about the values you refered to. hope you understand.
just re-reading your post several times about the ohms... so if my LED will run at 1v, my input is 5v, then...1V / 0.02A = 50 Ohm if i used a 50ohm resister, it should work? 1 / 50 = 0.02 which is 20mA ? if so then i think i understand that a little better.
