What is DC?
DC, also known as direct current, describes the flow of electrical current in a singular direction, moving from a positive terminal to a negative terminal. Unlike AC, which reverses its direction regularly, DC flows in a continuous direction. Batteries, electronic devices, and certain types of motors all operate on direct current.
DC power is produced by DC generators, which transform mechanical energy into electrical energy through the rotation of a wire coil within a magnetic field. The resultant voltage and current of direct current can effectively energize various electrical devices and equipment across a broad spectrum.
While DC has several advantages, such as simplicity, stability, and compatibility with many electronic devices, it also few limitations also, including higher losses over long-distance transmission as compared to AC.
Types of DC
- Unipolar DC
- Bipolar DC
- Low-Voltage DC
- High-voltage DC, etc.
Difference Between Ac And Dc
Alternating Current (AC) and Direct Current (DC) are two fundamental types of electrical currents. These currents differ primarily in the direction of the flow of electric charge. Direct Current (DC) flows continuously in one direction from the positive terminal to the negative terminal of a voltage source. Alternating Current (AC), on the other hand, reverses direction periodically.
In this article, we learn more about AC and DC current and how they are different from each other.
