What is Alternating (AC) Current?
How Does Alternating Current Work?
Before we talk about what the alternating current is, let us briefly describe what the current concept is. The number of electrons in metal atoms varies according to the type of metal. When we look at a conductive metal, there are less than 4 electrons in the last orbit. For a stable structure, it is necessary to complete 8 electrons.
If they can not complete, these electrons are released. Thus, there are millions of free electrons in conductive materials. When voltage is applied to these conductors, the electrons begin to move from negative to positive. This action is called Electric Current. Electric current is divided into Direct current and Alternative current. Now let’s talk about the alternative current.
What is Alternating Current?
Flow and alternation in a certain order of direction and intensity over time is called alternating current. That is, the alternative means the word meaning is a variable. It is briefly referred to as AC. The most known AC waveform is the sine wave. In the circuit with the direct current voltage source, the current reaches from the “+” pole of the generator through the resistance towards the “-” pole. There is no fixed “+” or “-” pole on the source if the A.C has a voltage source. Since the poles are constantly changing, the direction of the current flowing through the resistance at each polarity change will also change. In this way, flow is called alternating current, which changes direction and intensity according to time.
An alternative voltage source is called an alternative voltage source. Also the concept of the height of tension; when we are dry, our defense, which is a highly resistant one, protects us as well as that the tension is so high that we have to jump over the tops of the pole at Medium Voltage and High Voltage levels.
Where is Alternative Current Used?
Alternating current is used in large electric circuits and high power electric motors. Electricity in our homes falls into the category of alternating currents. The refrigerator, washing machine, dishwasher, air conditioner, and ventilator work directly with alternating current. Devices such as televisions, stereos, and videos use these alternating currents by turning them to the right flux.
The Effect Of Alternating Current On The Body
A current of 50 or 60 Hz passing through the body may cause a heartbeat, involving involuntary muscles. Secondary accidents, ie collapse after stunting, sudden contraction of muscles occurs. AC current is more accurate than direct current because it affects muscles.
If you increase the frequency of the AC current to 500 kHz or more, you do not have to touch the bottom of the capacitor. The effect of the current on the heart fibrillation is that the heat effect is felt from the beginning. The blood coagulates and the cells burst with the warming of the intracellular fluid. The cutting process begins. You can stop bleeding when you cut the tissue. How Does? This is done by modulating the sine wave with pure sine wave shape.
