WebAug 29, 2014 · Assuming a 95% conversion efficiency, the converter will draw 10 W / 0.95 ≈ 10.5 W, or I = 10.5 W / (12 V − U) amps, where U = 0.25 Ω × I is the voltage drop over the wire. Substituting the second equation into the first and solving, we get U ≈ 0.89 A, which is well within the capabilities of a 1 A wall wart. WebThe ac can be easily converted into dc. The variation of ac can easily be done using transformers either step up or step down. The value or magnitude of ac can be decreased easily without loss of excess of energy. This can be done by using choke coil. These are the 8 advantages of ac over dc. There are disadvantages of ac over dc also.
