In 1831, Michael Faraday discovered that when a conductor is moved through a magnetic field, an electric current is produced. This discovery led to the development of alternating current (AC), which alternates the direction of the current and can be transmitted over long distances.
AC is more efficient than direct current (DC) because it can be transformed to high voltages using transformers. This allows AC to be transmitted at lower currents, which results in less energy loss. Additionally, AC can be generated using renewable sources such as wind or solar power.
The main disadvantage of AC is that it can cause interference with electronic equipment. However, this problem has been mitigated mainly through filters and other devices blocking unwanted signals.
Alternating current (AC) is an electric current that periodically reverses direction, in contrast to direct current (DC), which flows only in one direction. AC is the form in which electric power is delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, although other waveforms, such as square waves and sawtooth waves, are sometimes used.
In 1882, Edison opened the world’s first central station on Pearl Street in New York City. It supplied 110 volts of direct current (DC) to 500 customers over a mile away. But DC had two major disadvantages: it could not be economically transmitted over long distances, and it was not easy to change voltage levels for different customer needs like lighting versus motors.
In 1887, Nikola Tesla filed a patent for an alternating current (AC) invention. This was a major breakthrough in the world of electricity, as it allowed for the safe and efficient transmission of electrical power over long distances. AC is now the standard electricity used in homes and businesses worldwide.
There are many advantages to using AC over other forms of electricity. One big advantage is that AC can be easily transformed to different voltages, which makes it ideal for long-distance transmission. Additionally, AC is less likely than direct current (DC) to cause dangerous electrical shocks.
Despite these advantages, there are some disadvantages associated with AC as well. One downside is that it can be more difficult and expensive to store than DC power. Additionally, certain electronic devices may not work properly when connected to an AC power source. Overall, though, alternating current has proven itself to be a reliable and safe source of electrical energy.
