Muhimmiya DC Votaji Da Yake Nufin?

DC votaji tana nufin "Direct Current Voltage". Wannan yana nuna cewa wannan sunan ya zama da amfani da ita a wurare don bayyana na gaba da jiki da tsawon karamin hukuma. Saboda haka, DC votajin tana nufin votaji da ya ba da shi ko za su ba da DC current. Amma, AC votaji tana nufin votaji da ya ba da shi ko za su ba da AC current.

A kan wanda nan, DC tana nufin abubuwa da ba su yi karfin tsawon karamin hukuma ko da zero (ko kuma near zero) frequency. AC tana nufin abubuwa da su yi karfin tsawon karamin hukuma a matsayin frequency mai kyau.

Voltage tana nufin electric potential difference per unit charge between two points in an electric field. Electrical energy tana samun ne daga movement and existence of charged particles known as electrons.

Movement of electrons tana create a difference in potential energy between two points. We call this potential difference voltage.

There are two types of electrical energy; AC and DC. As mentioned, the voltage acquired from the DC source is known as DC voltage.

DC voltage has a constant value. And it is denoted as VDC. The frequency of DC voltage is zero (or near zero). Hence DC voltage systems will not change their polarity during operation.

The Unicode character-U+2393 “⎓” is used for the DC applications. Sometimes, it is also symbolled as a straight line.

In a circuit diagram, there are several DC sources available to get DC voltage. A battery is the most commonly used source for a DC voltage.

The ideal DC voltage source has zero internal resistance. But an actual DC source will always have some amount of internal resistance.

In an ideal voltage source, the voltage drop across the source is zero. But in the case of a practical real-world voltage source, some amount of voltage drop occurs. This voltage drop increases as the current increases.

The VI characteristics of ideal and actual DC voltage source are as shown in the below figure.

Wiring systems are color-coded to identify individual wires. This type of system is most helpful to identify wires during maintenance activities.

The term “DC power” is often used instead of “DC voltage” when speaking about wire color codes (note: DC power is not interchangeable with the term DC voltage. But “DC power” is used more broadly to denote that the circuit
