AC and DC current both have useful advantages, depending on what you what to do with it.AC is more useful for sending long distance over transmission lines, as AC can be put through a transformer to change the voltage easily.All electronic devices work using DC only. Batteries provide DC and are readily available or can be created. All electronic devices, when used on a domestic AC supply, have their power converted from AC to DC, either within the device or an external power supply.More devices use DC than AC, but we could not get the power to where it is needed without AC transmission lines. Heavy motors were more efficient when constructed for AC supplies, but these days DC stepper motors are taking over, using electronic control circuits.
What else can I help you with?
Which is more useful ac or dc current?
both. it depends on the application.
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
Who is more popular ac DC or poison?
Ac/dc
Who is more famous Spider-Man or AC DC?
Ac dc
Who is more famous Mario or AC DC?
AC/DC of coarse! I don't actually know. I just like AC/DC
Who have sold more cds ac dc or metallica?
AC/DC, but only because there more widely known!
Why is AC better than DC?
AC power can be transmitted more efficiently than DC.
Which is more effecient an ac motor or a dc motor?
ac
Why do you study dc analysis first before ac analysis?
We do study DC Analysis first before AC Analysis for the sake of simplicity, for pedagogic reasons, and also for historic reasons. As useful and as easy to understand as DC is, it serves as a preparatory ladder in studying the more complex behavior of AC. In addition, it is to respect the historical sequence of events since DC sources were first discovered before the AC sources.
Why ac is more effective than DC?
because power dissipated in ac is less than power dissipated in dc.
who is more efficient dc motor or ac motor and why?
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
Why is AC used?
The power source is AC. Hence AC is used. DC application is limited.
