Thanks for the help gentlemen i really appreciate it. Just one more question. If the servo I am buying does not have a spec on current draw, could i just measure the resistance of the servo, and use Ohm's law? Is it applicable here or is the resistance constantly changing?
or is the resistance constantly changing?
It's not a good idea to just supply a bit more power than you need. Overestimate then double that and your PS will live longer. Same with a PC, always get extra power supply.
