compare AC and DC current which one is better and why
Answers
Answer:
ac(alternating current) and DC( direct current)
Explanation:
AC( alternating current) is better because it can be transported to long dist.
also,
in case of DC ,current flow in one direction.
in case of ac it flows in both direction...means it changes periodically
most of electronic devices in home works on DC
but the wire(main- red) to your home will have AC

DC vs AC: Direct Current (AC) Vs Alternating Current (DC)
Akash Peshin 1 Year Ago
The current (electric charge) only flows in one direction in case of DC (direct current). But in AC (Alternating current) electric charge changes direction periodically. Not only current but also the voltage reverses because of the change in the current flow.
The AC versus DC debate personifies the War of Currents, as it is now called, in which the two giants of electric power were embroiled in the late 1890s. Thomas Edison, the proprietor of Direct Current, was so threatened by Tesla’s invention that, in order to discredit Alternating Current, he resorted to falsely misleading Americans. Apprehensive about losing his royalties to this new technology, Edison went so far as to electrocute an elephant to show Alternating Currents’ fatal dangers.

However, this did not stop Tesla from fulfilling his dream of powering the United States with cheap and highly efficient energy. Even now, we see long and thick wires tightly strung between soaring electrical towers like the strings of a guitar. AC took over the throne and reigned for a century, dominating households, offices and buildings, until now, when DC seems to be gradually making a comeback.
