# 8 Advantages of alternating current over direct current

We all are aware of the concept of ac and dc. There are certain differences between two and also there are advantages and disadvantages or drawbacks of ac over dc. I will discuss the advantages in this article and disadvantages in the next article. Let us discuss them one by one.

1. We all know that we got ac supply in our homes and we got this supply by transmitting ac over long distances. AC can be transmitted using step up transformers but direct current or dc can not be transmitted by this method.
2. The ac is easy to generate than dc.
3. It is cheaper to generate ac than dc.
4. The ac generators have higher efficiency than dc.
5. The loss of energy during transmission is negligible for ac.
6. The ac can be easily converted into dc.
7. The variation of ac can easily be done using transformers either step up or step down.
8. The value or magnitude of ac can be decreased easily without loss of excess of energy. This can be done by using choke coil.

These are the 8 advantages of ac over dc. If you know more, please mention in the comment section.

AC current give shock but DC current don’t. So AC current is ssfe as compared to dc. This is the another advantage of ac over dc.

Thanks for valuable information.
AC current give shock but DC current don’t. So AC current is safe as compared to dc. This is the another advantage of ac over dc.

Select any topic from our Circuit Theory II course topics (eg, AC Analysis, Three Phase Circuits, Frequency Response Analysis, Magnetic Coupling Circuits or any topic defined in the Syllabus) to discuss its area of use, purpose of its usage, advantages and disadvantages in that field. Theoretically analyze any circuit model that can be used in that area. By using any design program such as Proteus (or any other such as circuit maker, pspice / orcad, matlab / simulink, etc.) get the same outputs and compare your results that is obtained from the theoretical one. Provide us shematics as well.
