AC / DC was born in Australia, founded in 1973 by brothers Angus Young and Malcolm Young. They were born in Glasgow, Scotland, then moved to Sydney, Australia in 1963. They classify themselves as rock music, but they are considered one of the pioneers of heavy metals. They are also one of the best boasting bands ever. "AC / DC" is an abbreviation, which means "AC / DC" power. They first got their sister Margaret's name, and Margaret saw the sewing acronym ACDC.
Where did Australian rock band AC / DC get their name? Of course, it is AC and DC. Both AC and DC represent the type of current flowing through the circuit. In direct current (DC), charge (current) flows only in one direction. On the other hand, the charge in the alternating current (AC) periodically changes its direction. Since the current changes direction, the voltage in the AC circuit is also periodically reversed. Most digital electronics you make uses DC. However, it is important to understand the concept of AC. Since most wired AC connections are used in most families, if you plan to connect the Tardis music box projector to the socket, you need to convert AC to DC. There are also some convenient functions for AC, such as the ability to convert the voltage level with a single component (transformer). This is why AC is chosen as the primary means of transmitting power over long distances.
Like rock bands, AC and DC power supplies also have a long history. Like DVD and Blu-ray (or VHS and Betamax in the elderly) these two have long been involved in competitive advantage. However, as energy can be provided in various ways, these two seem to have gathered recently to exist in harmony. Early American standards for the DC and power world developed by Thomas Edison involved the use of unidirectional flow. Unfortunately, we can not easily convert it to a higher / lower voltage, and let others seek alternative solutions: Nikola Tesla interaction. You can convert AC power to another voltage more easily using a transformer in the reverse direction of 60 times per second and 50 times per second (50 times in Europe). When the inventors compete for future relevance (and royalties) of the US power infrastructure, the "current war" continues.
AC (AC) and DC (DC) are known for stimulating the names of symbolic metal bands, but they are also in the center of the modern world we know. AC and DC are different types of voltages or currents used to conduct and transfer electrical energy. Fast - Think about the five things you did or touched in a day. You do not use electricity at all, do not use electricity, have no connection with the power inside your body, etc ... Well, you can do that. (Or, if you think so, please send me a list.
