THE DIFFERENCE OF AC AND DC CURRENTS IN VARIOUS ASPECTS

Before discussing the difference between AC and DC currents, we should remember a little understanding of electric current. Electric current is the electric charge that flows through the conductor at each unit of time. In the electric charge there are atoms of electrons and protons. Electrons have a negative charge in charge of carrying the electric charge to move to another place. Why electrons? because electrons can move freely from one atom to another in the conductor. There are 2 types of electric currents, namely AC current or alternating current, and DC direct current. The following is the difference between AC and DC currents.

  1. Differences Based on Understanding

  • AC Current (Alternating Current) AC electric current is an electric current that flows back and forth, AC current has varying directions.

  • DC Current (Direct Current) DC electric current is an electric current that flows in the same direction. This means that the electric voltage has a fixed value and direction. The flow of electrons in the DC current moves in one direction (forward).

     2. Difference Based on Frequency

  • AC Current In AC current, there are frequencies that have different magnitudes. AC current is the electric current that we use in our daily use of promir. For example television, refrigerator, house lights and electric stoves. The standard voltage for AC or alternating current is 220 volts, while the frequency set by Indonesia is 50 Hz.

  • DC Current The frequency contained in the DC current is 0 and the electricity in the DC current flows from the negative pole to the positive pole. DC currents are also widely used for everyday electronic equipment.

     3. Difference Based on Strengths

  • Excess AC Current Has a relatively small disadvantage, so that AC current is used to supply electricity to distant destinations. Using a high voltage uses a transformer so that it can be distributed to distant places. AC current is easy to obtain, with the help of an AC current generator it is easy to obtain.

  • DC Excess Current DC electric current can be stored, usually in the form of batteries or batteries. DC current can be recharged (refilled), can be used as a backup.

     4. Difference Based on Disadvantages

  • Lack of AC Current Although it is easy to get it, AC electric current cannot be stored like DC current (battery, battery) and cannot be moved.

  • Disadvantages DC does not have high power, so it cannot be flowed over a long period of time.
The following is an example of the difference between AC and DC currents

Series circuit and Parallel circuit

Gambar
Series circuit The series of electrical circuits consists of several resistance components that are connected between one component and another in a row, and in the electrical circuit in series there is only one line used to drain electricity so that if one component is damaged it will affect the electricity flow leading to the next component. Series series have no branches. In other words, a series is a circuit whose electric current flows on only one line. Series series are formed when electric current is connected in sequence or in a row. The negative pole of the first component with the positive pole of the second component, the negative pole of the second component with the positive pole of the third component, then passed to the positive pole of the first component.  In  series, the strong electric current that flows through some electrical barriers is equally large. The amount of strong current on the series series is not affected by the resistance value. If there a...
