Do you know electronics? If so, I have a question:

Question 1.
Let's say you have some LED's, maybe 5 or 10. They are all the same type and voltage,but you don't know what type or voltage they are - you just know they are all the same.

If you connect them all in parallel, is there a way you can test the new circuit to know how much voltage & amps are required to light them all?

Question #2:
Same question as above, but the LED's are various types. Some are older (red), some are new (blue). Some are larger, some are smaller. The volts / amps required for each of them are unknown.

If I connect them all in parallel and want to light them, how can I measure to know what kind of power supply (and how many volts and amps) is required?

HNY!
