Diferencia Entre Corriente Alterna Y Continua
What is the difference between AC and DC? 3
The difference between AC and DC, so DC only rotates in one direction.
The alternating current (indicated by the number) briefly rotates in one direction and then in the opposite direction, repeating the same process over and over again.
This type of electricity reaches our homes and we use it to power our TVs, sound systems, washing machines, refrigerators, and so on.
The graph below shows a voltage (which also changes) and its intensity varies first up and then down (as the current behaves) gives us a flat viewform: a sine wave.
The voltage is constantly changing, and to find out what voltage we have at any given time, we use the formula V = Vp x Sin (ŽÂ˜), where Vp = Vpeak (see graph) is received from the waveform. The maximum value is 2 angular distances and is measured in degrees.
If you make this last part a little clearer and enlarge the graph, you can see that a sine wave is continuous (you repeat the same wave over and over again).
When the period is taken away from it (full cycle), it is cut into squares with a 360 degree angle space.
And with the help of our given formulas, including (the angular distance for which we want to know the voltage), we get the actual voltage in which we are interested.
For each different angle distance, the value of voltage varies, some positive and some negative (if the polarity is reversed).
First we need to explain the entity: DC entity has a negative and a positive relationship. When these terminals are connected to a circuit, a one-way direct current flow is generated and with a fixed value which depends on the value of the voltage in the unit and the resistance of the circulating circuit, ideally this change Is sinusoidal.
Electric current flows in a current, circulating in the conductor, always in the same direction, as if it were a liquid in a pipe. In the alternating current discovered by physicist Nicola Tesla, the polarity of the current bed is about 50 times constant.
The alternating current is normal domestic, there are 3 neutrals and faces and there is no sense of alternating motion, if electrons come and go through the same three pole connection from three phases and if there are monophysics through faces and neutrals , DC. There are continuous cycles and from positive to negative, it is common to see it in cars. With the latter, you can move like an elevator brake, but it's okay to change it. Happiness
Changes in the value of current changes over time, this is a periodic signal, usually a sign ...
Direct current never has a value, it is always the same over time, it is a constant value.
