ac transmission are used because we easily step up the voltage as per our requirment and also breaker used for ac break the ac current easily bcs of nature of zero current at every cycle
but for long distance transmission done by dc due to reducing the skin effect and also reduce the relative inductance of the line due to this the line losses are reduce and we transmit the more power.

∙ 13y agoAc/dc is a band, ac is air conditoning, and an acto dc converter has something to do with electricity

∙ 12y agoac refers to alternating current and dc represents for direct current. in ac current, its frequency changes with time whereas in dc its frequency doesn't change with time.

∙ 12y agothe difference between ac and dc is that the curren on ac is moving alternative and on dc is moving directly

What county is ac DC is from?
AC/DC are from Sydney, Australia.
What year did ac DC's group start?
ac/dc started up with Bon Scott in 1967
How do you spell AC DC?
Most people think that you spell AC DC like A-C-D-C. But really, the abbreviation is spelled A-C-Lightning bolt-D-C. It's a common mistake. LOL. |{.|{. That's all.
How many fans do AC DC have?
a lot
Where did ac-dc originate?
The band formed in Syney Austailia
What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
Why not you use ac instead of dc to electronic components?
AC is easier and cheaper to send from the generators to the consumers than DC is.
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
Can you use AC instead of DC for superposition theorem?
Yes, the theorem still applies for AC.
Will value of J be same if ac were used instead of dc?
The number of Joules (energy) is the same as dc provided the RMS values of the ac quantities are used.
Why does modern hybrids use ac synchronous motor instead of dc series motors?
Toyota uses AC motors, Honda uses DC motors. It varies with design goals.
Why cant you generate DC directlyinstead of generating AC and converting it to DC?
Yes, by using a dynamo (which produces d.c.) instead of an alternator.
Why we used ac volt in supply line instead of dc volt?
AC voltage is more sufficient than DC voltage. Moreover, an AC transformer can be developed but DC voltage will make it harder. Without a transformer, we cannot turn the high and low voltaged into each-other.
Is there any possibilty of ac and DC flows in conductor at a time and get DC and AC with two reference AC and DC?
A typical AC waveform is symmetrical about a zero crossing point. You can bias the AC with DC such that the AC waveform is symmetrical about the DC voltage.
Ac to DC formula?
formula for ac to dc
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What will happen if you use AC voltage instead of DC voltage?
For some equipment it doesn't matter, other types of equipment will be destroyed. For a simple electric heater or an incandescent bulb AC or DC are acceptable, provided the rms voltage of the AC is equal to the DC voltage. If the heater has a time switch, DC is unacceptable. A DC motor may or may not work with AC depending on its type and size. The commutator motor as used in vacuum cleaners is essentially a DC motor, but most types of AC motor are not interchangeable to DC. Electronic circuits usually required a DC supply and if AC is applied many of the components will be destroyed.
