WHAT IS THE DIFFERENCE BETWEEN ALTERNATING CURRENT AND DIRECT CURRENT POWER?

Before we talk about Alternating Current and Direct current, it is essential we talk about what electric current is.

What is Electric current?
Electric current is defined as the flow of electric charge in an electrical circuit. Power is being carried by moving electrons in a wire also called ions in an electrolyte. Since we talked about electric current, we should now move to the types of electrical current that we have.

Types of Electric current
1.    Alternating Current
2.    Direct current

Alternating Current
This describes the movement of flow of charge in a periodically reverse direction.  An alternating voltage is a voltage that is transmitted to business facilities and residences. The typical waveform associated with an Alternating power is known as the sine waves. Other waves related to with Alternating power are triangle waves, square waves, radio waves and Audio signals carried in an electric wire are also called Alternating current.

Direct Current
Unlike the Alternating Current, the Direct current is a unidirectional flow of charge. This is a movement in which charge moves only in one direction. Direct current is present in batteries, solar cells, thermocouples. Direct current can also be created by converting an Alternating Current using a rectifier into a unidirectional flow of charge. It can flow through wires, conductors, semiconductors. They can also flow through insulators but it is not easy like that.
 
Difference between alternating current and Direct current
We’ve discussed the Alternating Current and Direct Current, so discussing the differences is very straightforward.
  • Alternating current is the flow of charge in a periodically reverse direction (to and fro) while Direct Current is unidirectional flow of charge either forward or backward.
  • Regarding waveform, Alternating current displays either sine wave, triangle wave or square wave depending on the circuit while DC only display a straight horizontal line when a voltage is plotted against time.
  • Regarding energy that can be transmitted, an alternating circuit is safe to be transferred over a long distance and will provide more power. In the case of Direct current, technically, the voltage of DC cannot travel very far until it begins to lose energy.
  • In terms of the Frequency, Alternating Current will either be 50Hz or 60Hz depending on the location while for Direct current, the resonating frequency is zero
  • Source: Alternating current is generated for an AC generator while Direct Current is generated from a battery or cell.
  • Talking about Power factor, Power factor is defined as the ratio of the real power moving to the load to the apparent power in the circuit. With this definition, the difference between alternating current and Direct Current regarding power factor is that for Alternating Current, the power factor lies between zero and one while in a Direct Current, it will be pulsating and pure.
The significant difference between Alternating current and Direct Current is the flow of Charge. If you are looking to install new electrical devices or appliances, it's best to hire an experienced electrician to ensure all your new purchases are installed correctly.

How To Install A Ceiling Fan For Your Home Or Business

Installing a new ceiling fan is a great weekend project for any DIY-er as it will only take you a few hours to complete and the payoff is immediate. Step 1: Turn off power Be sure to turn off power to the existing light or fan at the main fuse or circuit box. Use a circuit tester to verify that the power is off, while also turning the corresponding wall switches to the off position. Step 2: Determine what switches you need If this location has dual-switch wiring (where one switch controls the light and a separate switch controls the fan), label the wires accordingly so you won’t get confused later. If your electrical box has wiring for separate light and fan switches but you will only be using the fan switch, trim off the bare portions of the wires for the light, attach wire connectors to the ends, then wrap with electrical tape. Pro tip: if you plan to control the fan with a wall switch, check to make sure you have the right kind of switch. Some fans will only w...

Advantages Of Installing Ceiling Fans In Your Home

There are numerous advantages of installing ceiling fans that go beyond the obvious fact that they are primarily meant to cool off a room. Using them throughout a home not only cuts down on energy costs but also provides style and beautiful lighting as well as comfort. Ceiling fans have numerous benefits both function wise and fashion wise. They include: Cuts Down On Energy Costs Even though they do not actually lower the temperatures, ceiling fans help lower electric bills by up to 30-40% as they make a room feel cooler enabling one to raise the thermostat without any discomfort. They Are Stylish Accessories There are several varieties of ceiling fans available that can give your home that unique interior décor you want. They vary in styles, finishes and sizes from which you can choose one that compliments your décor. They can serve as a focal point or as a statement piece in a room. They Offer Versatility From One Room To Another Whether the bedroom, kitchen, screened-in po...

Why it's important to use a licensed electrician to complete your kitchen lighting renovations

When you are thinking of getting renovations to your Kitchen lighting, it's important to ensure that the electrician is licensed and certified correctly. This is due to the nature of the work, if mistakes are made, you pretty much just paid to make your home much more dangerous. Low quality work will result in a low level of safety and that is something nobody wants to pay for. Even more than that, in most cases, you will find that you will be paying the same amount regardless of whether or not they are licensed or not, so why take the risk? Another factor to take into account is the fact that this can have an impact upon an insurance claim should there be a fire or some other kind of disaster. Hiring an unlicensed trade worker will result in not only a more dangerous environment, but should your worst fears be realized it could very well cost you the entire value of your home! Something that I am certain nobody wants. When getting work done, most people put costs first. This c...
