Hello, guys welcome to the new post. Here we will discuss Difference Between Alternating Current (AC) and Direct Current (DC). AC current changes its polarity after some time interval and dc has constant polarity. AC has some value of frequency and no frequency exist for dc current.
In this post we will see different parameters to finds the differences between AC and DC current. SO let get started Difference Between Alternating Current (AC) and Direct Current (DC).
Difference Between Alternating Current (AC) and Direct Current (DC)
What is AC Current
- AC is current that varies in direction periodically and magnitudes than the dc current.
- AC current gives the power to the loads like homes businesses and industries.
- It is the type of electrical energy the users used to run the load like TV, kitchen appliances, heater fans, and lamp
- The waveshape of ac current is a sine wave that is positive and negative after some time
- In different applications like amplifying other shapes of ac current like triangular, square waves are used.
- This ac signal is used to transmit information like audio waves as well as video and also used as modulation.
- Electrical energy transmits in form of ac current since AC volts can be increased and decreased through use of transformers.
- So power transmits through a transmission line having larger volts that decrease the power losses due to heat generated of wire resistance.
- The value of frequency for AC is 50 or 60 according to the country.
- Electron flows in ac are bidirectional
- Its power factor lies between zero and one
- ALternators produce the AC current
- It can run the inductive capacitive and resistive loads
- It can be transformed to dc through use of a converter
- There is a need of a substation for the generation and transmission of ac current
- It can be dangerous but less than the dc
What is DC Current
- Dc current is the single-direction flow of charges. An example of dc power production is an electrochemical cell
- It can flow through conductive wires and also through semiconductor devices, and insulators.
- It flows only in a single direction. Dc current also called galvanic current
- Rectifiers are used for conversions of dc to ac and inverters are also used to ac conversion
- It is used in different applications such as battery charging to give power to different loads like motors, and electronic devices.
- It is used for smelting of aluminum and electrochemical process and used in railway
- It has zero value of frequency
- Its flow direction is constant not change polarity
- Its power factor is one
- Produces by the battery and generators
- Its graphical representation is a straight line
- It can be transmitted to longer distances with fewer losses
- It can transform to ac.
- Common applications of dc are
- Mobile phones phones
- The LilyPad-based D&D Dice Gauntlet
- Flat-screen TVs
- Hybrid and electric vehicles
That is all about the Difference Between Alternating Current (AC) and Direct Current (DC). All details have been explained if you have any further query ask in the comments. Thanks for reading have a good day see you in the next post.
