Need Some Electrical Expertice

[FCIN]

Milli = 1/1000, so you are correct. 5000 mA = 5 amps. That transformer will work fine - but bear in mind the output will be 14 V AC

Glad to hear that my electrical knowledge wasn't too far off. The transformer I mentioned converts the AC to DC output so the bridge rectifier isn't an issue.
Thanks!
