ac and dc current difference


Homes are usually powered by AC currents. anon133951 December 13, 2010 He built a first power plant The symbol of DC and AC current is as shown in the figure below.The electrical energy is available in the form of Alternating current (AC) or Direct current (DC). It is said that Edison went to great lengths to make AC current unpopular, including killing animals with AC current to make people feel that it is dangerous.

The result obtained will be, the voltage level also reverses along with the current. When the time varies the waveform also varies.The φ describes the phase of the sine wave.

The major differences between Alternating Current and Direct Current are given in the table below: Alternating Current Direct Current; AC can carry and safe to transfer longer distance even between two cities, and maintain the electric power. anon146846 January 27, 2011 . Direct current is a little bit easier to understand than AC current because DC provides a constant voltage or current. Basically, AC is used to deliver power to industries, houses, office buildings, etc. i really want to know. Each battery is designed to produce only one voltage, and that voltage of DC cannot travel very far until it begins to lose energy.

Generating DC.

DC can be generated in a number of ways: An AC generator equipped with a device called a "commutator" can produce direct current In this scenario, AC can be converted to DC. Therefore, high-voltage DC currents are also occasionally used to transmit power.The War of Currents: Edison (left) wanted to distribute electricity using DC, while Tesla (right) wanted to distribute electricity using AC.“Thomas Alva Edison, three-quarter length portrait, seated, facing front” by Louis Bachrach, Bachrach Studios, restored by Michel Vuijlsteke ( United States Library of Congress’s Prints and Photographs division digital ID cph.3c05139) [Public Domain], via “A photograph image of Nikola Tesla (1856-1943) at age 34.” by Napoleon Sarony (postcard (

For this sine wave, the three things which are required are amplitude, phase, and frequency.By looking at just voltage, a sine wave can be described like the below mathematical function:The function of sin( ) states that the voltage will be in the form of a periodic sine wave and will act as a smooth oscillation at 0V.Here 2π is constant. AC is an acronym of Alternating Current while DC is an acronym of Direct Current.The major difference between AC and DC is that DC is unidirectional current while AC is bidirectional Current.

When the electricity was invented many changes have taken place over the years. Most of the solid-state equipment requires a voltage range between 1.5 and 13.5 volts. In alternating current, the current reverses direction 50-60 times in a second depending on the The DC current can easily get from the battery and solar cells. It converts the frequency from cycles in hertz to angular frequency in radians per second.Here f describes the sine wave frequency. However, for alternating currents the voltage can be characterized by a single number called the Root mean square (RMS) voltage and maximum (peak) voltage for a sinusoidal voltageOften, the power dissipated by a component is calculated using the RMS voltage. "AC vs DC (Alternating Current vs Direct Current)." DC is constant with time while AC changes at every instant of time. The description of the Sine waveform is discussed below.Generally, the AC waveform can be understood easily with the help of mathematical terms. But they are very different. Main Difference – AC vs. DC Current. The periodic nature of the sine wave shifts by 360° it becomes the same waveform when shifted by 0°.For the above formula, the real-time application values are added by taking the United States as a referenceRoot mean square (RMS) is another small concept which helps in calculating the electrical power.The other waves, i.e. triangle and square are shown below:Direct current (DC) is the movement of electric charge carriers, i.e. The solar panel converts sunlight to DC power and we store it battery then we convert this DC power to AC power by an inverter for our demand.
