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.

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
Lightning carries Alternating current or Direct Current?
Power lines carry electricity as alternating current.
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.
Current from a battery is always?
Direct current, as opposed to alternating 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.
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 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.
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.
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.
What is direct current and alternating current?
Direct current is a constant, steady state current, such as obtained from a battery. Alternating current is constantly switching polarity, usually in a sinusoidal waveform, such as obtained from an alternator, a form of generator that does not have a commutator.Direct Current and Alternating Current:The first and simpler type of electricity is called direct current, abbreviated "DC". This is the type of electricity that is produced by batteries, static, and lightning. A voltage is created, and possibly stored, until a circuit is completed. When it is, the current flows directly, in one direction. In the circuit, the current flows at a specific, constant voltage (this is oversimplified somewhat but good enough for our needs.)The other type of electricity is called alternating current, or "AC". This is the electricity that you get from your house's wall and that you use to power most of your electrical appliances. Alternating current is harder to explain than direct current. The electricity is not provided as a single, constant voltage, but rather as a sinusoidal (sine) wave that over time starts at zero, increases to a maximum value, then decreases to a minimum value, and repeats.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
