Hey,Thanks so much for the quick reply and for pointing out that it outputs AC no DC since that would not have ended well! And also just for future reference, if it outputs about 8amps and my project only requires lets say 4amps will this matter? Or does it only matter if my project requires more than the 8amps? No a voltage source can not force a specific current into a load, but rather allows the load to draw what current it requires according to ohms law. Voltage sources rated their current output as the maximum it can supply, but if can of course supply anywhere from 0% to 100% of that current rating.Also was there a specific calculation you used to change the watts into amps?If you know the watts and the volts, then amps = watts divided by volts. This however does not account for small losses that would not allow for 100% efficient power transfer across the transformer. Most well constructed transformers work in the high 90%+ range.Thanks again!
Brilliant thanks, so if I need 5amps I should go for maybe 5.5-6amps to cover possible loss?
That's fair enough and makes sense I guess as it also allows for human math error, and future expansions! As for the PC power supply, could you show an example as I am concerned about the size of the for my project and I am really keen on this one (http://www.ebay.co.uk/itm/AC-100-240V-to-DC-12V-Switching-Power-Supply-Regulated-Transformer-for-LED-Light-/230844619265?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item35bf695a01&_uhb=1#ht_3557wt_1037).Thanks again!
