Because electroplating brings ions out of solution on to a surface. With ac the ions do not get deposited, they just move to and fro.
AC current can flow through a capacitor, it's DC current that can't
Cant. Fan on computer runs on house current (power) which is AC and the car has a DC (direct current) power system.
AC
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
A "Rectifier" converts AC current to pulsating DC current.
The power transmission would require bigger wires to transmit high dc current so instead high voltage ac current is transmitted through long distance linesTo reduce losses it is necessary for the value of current through lines to be lowTranformers donot work for dc current so one cant step up and step down dc current voltage like it can be done with ac current
ac current
ac stands for alternating current so ac current means alterneting current current. its like entering your pin number on an ATM machine.
ac
unfortunatley i cant tell for sure what you mean because of the lack of grammer (not insalting you) but if your asking wether it has direct current (DC) or alternating current (AC) like i think you are than the answer is direct current (DC)
AC means alternating current DC means direct current there is no polarity reversal
AC, Alternating Current.
