Disadvantages of DC:
* High power transformation of voltage is less convenient than AC. AC uses a transformer.
* DC does not have the natural break in transmission that AC has (zero twice per cycle) and does not switch off as easily
* DC does not provide time to synchronous clocks * DC dynamos or generators are less efficient at converting input power to output electricity than AC alternators. That is why altenators with rectifiers are now used in vehicles instead of DC dynamos.
What else can I help you with?
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
What is DC in electric stand for?
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply
Why power factor is not present in direct current?
There is no angular gap between voltage & current in Direct Current. So power factor is always cos 0 deg. i.e. 1 for all tha cases of DC.
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
Which type of current invovles flow of charge in two directions?
A direct current involves change of flow in a single direction. DC (direct current), at least on the macro scale. On the atomic scale, they seem to wander all over the place between atoms, and the average movement is what we measure as current.
Does a flashlight use a direct current of electricity?
Yes, all batteries provide direct current.
What drawbacks are associated with direct email marketing?
A drawback to direct email marketing is the high failure rate to deliver an email to a potential customer. Around 50% of all direct emails from marketers fail to reach their potential costumer.
What are the disadvantages of the direct metnod?
Could be unreliable as you don't know what could be the drawbacks
Merits and demerits of direct current distribution?
In direct current the voltage and current remain the same at all times. Direct current is more efficient when traveling longer distances, but has a higher loss rate when distributing to many people and its much harder to change the voltage.
Will a battery supply direct current or alternating current or ac?
direct current.
what is dc enerygy?
Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change. It is used in many household electronics and in all devices that use batteries.
How many types of direct current and what is the frequency of direct current?
There is only one type of direct current and its 'frequency' is zero.
What are two reasons for analyzing data?
to plan for the future on sound and good basesto put fingers on any drawbacks in the current business attitudes and correct for these drawbacks.
Which would make more shock the alternating current or direct current?
direct current
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
Current that doesnt reverse direction is called?
direct current
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
