AC-DC Voltage; What’s the difference ?

5 Flares 5 Flares ×

In our daily life we all keep hearing terms like “230V AC power plug”, “AC to DC power supply” and “1.5V DC battery”; however only very few people know and even actually understand the difference between AC and DC current. Through a search engine it is very easy to find that AC stands for “Alternating Current” and DC stands for “Direct Current”, yet understanding their actual differences can prove to be quite the task.

In this editorial we will try to explain the main characteristics and differences of AC and DC current in terms understandable by people with very low or no technical expertise.

    ermmm. I was excited on the first page, 2 and 3 pages were good, 4th page, still struggling to break it all down. I suppose we need some skills with eletrics in the first place.

    Very very very interesting article, mostly because I just had my physics exam, so I don’t hate this kind of things anymore! :D
