Ok, I have to build a simple power supply that will allow me to run this motor:
http://cgi.ebay.ca/9V-DC-Water-Pump...umps?hash=item5d26743a41&_trksid=p3286.c0.m14
Now, on the auction it says that the maximum current the water pump takes is about 4 amps at 12 VDC. Now I do have some experience designing simple power supplies, but nothing with a lot of current.
Does this mean that the transformer I pick will have to have an output current of about 5 amps or so or what factors do I have to pay a lot of attention to when picking a transformer in this case.
