Please help! How do I lower the current strength (Amps) in a parallel circuit so I don't fry my LEDs? Answered
I have a AC/DC adapter that gives out 4.5V and 500mA, how could I lower the strength of the current so that I can connect four LEDs (4.5V, 20mA) in parallel and not fry them? Sorry if I ask the impossible, I'm a total electric beginner.
Thank you in advance!
