ac is better than dc?
450152
When transferring electricity over great distances, AC is better than DC because of the simple methods we can use to step up and step down voltages. Transformers have the ability to do this with AC but not DC, or at least much less complicated than DC. For the purpose of example, say I need 120V with 100A capacity.

No difference. both are same there is no ac and dc cable i mean there is no specific cable to be used for both individually. Any conductor works for AC will work for DC too.

DC circuit breaker, like their name suggests, is used for the protection of electrical devices that operate with direct current. The main difference between direct current and alternating current is that in DC the voltage output is constant, while in AC it cycles several times per second.

Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

Fans can run on both AC as well as DC according to the circuitry used inside it. ... As our power sources are AC , so we have to convert a AC motor fan to DC to be able to use. DC fans consume 70% less power than the AC fans.

AC vs DC (We only sell AC Ballasts): Both types of ballasts take the DC power from vehicles and power the HID bulbs for light. The difference in these ballasts is in the type of electricity being outputted to the HID bulb. AC ballasts output AC power, while DC ballasts output DC power.

In DC, the electrons flow steadily in a single direction, or "forward." In AC, electrons keep switching directions, sometimes going "forward" and then going "backward." Alternating current is the best way to transmit electricity over large distances.

A.C. is More Dangerous than D.C. A.C. is said to be four to five times more dangerous than D.C. For one thing, A.C. causes more severe muscular contractions. ... The frequency of the AC has a lot to do with the effect on the human body. Unfortunately, 60 cycles is in the most harmful range.

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long distances. ... Thus, the majority of transmission lines carrying power around the world are of the AC type.

Difference Between AC & DC Bridge. One of the significant difference between the AC and DC bridge is that the AC bridge is used for measuring the unknown impedance of the circuit whereas the DC bridge is used for measuring the unknown resistance of the circuit.

The Difference Between AC Fans & DC Fans. The direct current fans, or DC fans, are powered with a potential of fixed value such as the voltage of a battery. ... In contrast, the alternating current fans, or AC fans, are powered with a changing voltage of positive and of equal negative value.

But it does offer moderate savings on your electric bill: Vornado claims it's 80 percent more efficient than similar AC-powered fans, which our testing confirmed—as long as you're not constantly running it on high.

Here, the difference between 3 star and 5 star ac is 2 star ratings, that is 5 star ac saves up to 28% more energy than 3 star ac. As we use the air conditioners regularly in the summer, our power bills tend to be on the higher side.

Yes they are equivalent and as Phil notes 100V DC is equivalent to 100V AC RMS. 100 V DC will produce the exact same average power as 100 V AC RMS. This is why the RMS values are used on all appliances and equipment.

AC is easier to transform between voltage levels, which makes high-voltage transmission more feasible. DC, on the other hand, is found in almost all electronics. You should know that the two do not mix very well, and you will need to transform AC to DC if you wish to plug in most electronics into a wall outlet.

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.

Classic rock is more of an umbrella term for all older rock. They could fall under either classic rock or hard rock, but not metal. AC DC is Alternating Current and Direct Current :O. Classic Rock to me--my favorite genre of music.
