Why AC is used for generation and distribution?

Alternating Current is used for electric power distribution because it can easily be transformed to a higher or lower voltage. Electrical energy losses are dependent on current flow.

Why is AC preferred over DC for transmission and distribution of electricity?

Answer: Ac is more preferred than dc because it is easy to maintain and change the voltage of ac for transmission and distribution purpose. Plant cost of ac transmission is much lower compared to dc transimission. When fault occurs it is easy to interrupt ac supply.

How is AC power distributed?

There is no definite line between transmission and distribution according to voltage or bulk capacity. However, in general, the a.c. distribution system is the electrical system between the step-down substation fed by the transmission system and the consumers’ meters.

Why is AC power used instead of DC?

Simply put, AC voltage is capable of converting voltage levels with just a transformer, making it far easier to transport across great distance than DC, whose conversion requires more complex electronic circuitry. Electric charge in AC periodically changes direction, causing the voltage level to reverse.

Which is more efficient AC or DC?

DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to size characteristics. The greater efficiency resulting from recent developments in DC converter technology allows improvements in electricity delivery over long distances.

What is the advantage of AC power transmission?

AC power transmission is cheaper and more efficient in voltage stepping using transformers. This leads to efficient electrical energy transmission through power lines. This efficient transmission helps power companies and the consumer to save lots of money.

Which is worse AC or DC current?

AC current is said to be more dangerous than DC current because the root mean squared value of AC is much more than its original value. Our heart is driven by electric pulses; the high electric frequency of AC current can affect the frequency of the heart and can lead to a heart attack.

Why AC is cheaper than DC?

Now the choice for AC or DC will depend on the cost of equipment needed to increase and decrease voltage level. As the transformer and related equipment for AC are cheaper compared to boosters and converters for DC, AC supply system is less expensive and accepted world wide.
