Who is the main target for AC DC?

The main target of AC AND DC IS TO GIVE SUUPLY TO CONUMERS WERE AS AC CURRENT IS CHEAPER COMPARING WITH DC


What is the Purpose of an ac welder?

It produces alternating current AC. It is cheaper to build than a DC or an AC - DC welder. Most electrodes can be used with DC. Some can be used for both. Very few are AC only. DC produces a smoother arc, is easier to strike an arc and most machines in industry are DC. Surprisingly a lot of AC machines are on farms as they were cheaper to buy.


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.


Advantages of Ac to DC converter?

some things requre a dc (direct current) rather than an ac (alternating current)


Why ac prepared DC current?

because the transmission cost of ac supply is lesser than dc. thats why ac is prefered


What device converts dc current to ac current?

A "Rectifier" converts AC current to pulsating DC current.


Why ac current is more dangerous than dc?

no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock


What is the sign for ac and DC current?

AC means alternating current DC means direct current there is no polarity reversal


Is DC or AC current faster?

AC current is not necessarily faster than DC current. The speed of current flow depends on the specific characteristics of the circuit and the components involved, rather than the type of current being used.


Is DC is at low voltage than ac?

There's no correlation between the voltage, the current, and whether the source is AC or DC.


What is strong the DC or the ac?

DC, or direct current, is stronger than AC, or alternating current. The reason for this is because DC current is smooth and unvariable as opposed to AC which varies from zero to whatever the maximum is, and then goes back to zero once again.


What is cheaper to buy ac or dc welder?

A dc welder is a lot cheaper by fair of the two
