AC means alternating current and DC means direct current.
The amplitude of AC voltage and current varies with time. Traditional AC electricity used in homes in the United States is a 60 Hertz sine wave. This means that 60 cycles of a sine wave occur every 1 second.
Since AC voltage varies with time, the amplitude at each instant is different. The voltage changes from 0 to +Vpeak to 0 to -Vpeak and so on. Since the amplitude is always changing, the voltage quoted for AC such as 120 Vac for US homes is an average known as the Root Mean Square (RMS). The general formula for determining the amplitude of the voltage at any given time is:
Vinst = Vpeak x sin(t)
where Vinst is the instantaneous voltage at time t, Vpeak is the peak voltage, and t is the time.
The relationship between Vrms and Vpeak for a sine wave is given by the formula Vrms = Vpeak / square root (2), so Vrms = Vpeak x 0.707
DC electricity does not vary with time. The voltage and current are constant at all times.
What else can I help you with?
If 200V AC generator connected to 200V DC generator then what happens?
current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
A multimeter can measure?
A multimeter is used for measuring electricity and because it has many different functions, it has been named a "multi"meter. They generally measure AC and DC voltage, amps, and resistance (ohms).
Generators can produce two types of electric current?
Absolutely! Generators can indeed produce two types of electric current: alternating current (AC) and direct current (DC). Let me break it down for you. First up, we've got Alternating Current (AC). This is the kind of electricity you'll find in most homes and businesses. AC changes direction periodically, meaning the flow of electrons alternates back and forth. It's like a little dance where the electrons keep switching partners, and it's super efficient for transmitting electricity over long distances. That's why the power from your local utility company is usually AC. On the flip side, we have Direct Current (DC). This type of current flows in a constant direction, like a straight line. You'll find DC in batteries – it's the juice that keeps your gadgets powered up. While it's not as great for long-distance transmission, DC has its perks, especially for certain electronic devices that prefer a steady and unchanging flow of electricity. So, in a nutshell, generators can play both sides of the current game, producing either AC or DC, depending on the application. It's like having a versatile musician who can rock out with different tunes depending on the audience. Cool, right?
How can you make an electromagnet stronger?
More wire wrappings, Larger Iron core, more and stronger electricity, etc
Why cant a 18V battery be used as the input of a transformer?
The transformer needs AC at its input. The battery provides DC.
Is electricity AC Or DC currant which one?
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
Car electricity uses ac or DC?
DC
Which choice defines AC and DC correctly?
Choice of electricity defines ac and dc
What doaes ac DC stand for?
The two forms of Electricity are AC and DC. AC Stands for Alernating Current and DC stands for Direct Current. AC electricity comes out of the Powerpoint that your computer is probably using and DC electricity is used in 5.1 voltage batteries that probably power your flashlight or toy.
Is the electricity from batteries AC or DC?
Direct current
Is New Zealand mains electricity AC or DC?
AC 220/240 volts
Is ac-DC good?
acdc is the best freakin' band ever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!but if your talkin about electricity that's good to
How do diodes converts ac electricity to dc electricity?
by blocking current flow in one direction
How do diods convert AC electricity to DC electricity?
by blocking current flow in one direction
Is it diesel generators is DC or AC generators?
Most diesel generators are designed to produce alternating current (AC) electricity. However, there are some diesel generators that can also produce direct current (DC) electricity with the help of rectifiers or inverters.
What are the advantages of AC and DC electricity?
AC electricity will not dissipate in charge traveling along a wire for up to hundreds of miles whereas DC dissapates at about 2 miles at its best. DC is simple and easy, the simplist electrical cirtuit possable.
What is the definition of AC-DC converter?
AC-DC converter such as a convertor by which we can convert alternative currents into direct current & its vice-versa. ...... anil allahabadi
