What is the frequency of AC current?
The Basics of Alternating Current. The most common frequency of alternating current is 60 cycles per second (usually termed 60 cycles) or more commonly, 60 Hertz (Hz).
What is frequency of AC and DC?
The frequency of AC is depended upon the country. But, generally, the frequency is 50Hz or 60Hz. DC has no frequency of zerofrequency. In AC the flow of current changes its direction backwards periodically. It flows in a single direction steadily.
Why frequency of AC is 50hz?
We should be aware that why use 50Hz or 60Hz, rather than lower or higher frequency. ... The frequency of alternating current is 50(60) Hz, the current direction changes 50(60) cycles, 100(120) times per second. The electric motor is made according to the basic principle of the rotating coil in the magnetic field.
Is 50hz better than 60hz?
50Hz vs 60Hz in operating speed
The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is, well, 60Hz is 20% higher in frequency. ... Lower the frequency will be the iron losses and eddy current losses. Lower the frequency, speed of induction motor and generator will be lower.
What happens increase frequency?
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true—as frequency decreases, wavelength increases.
What is the frequency of India?
50 Hz
What voltage and frequency in India? In Indiathe standard voltage is 230 V and thefrequency is 50 Hz. You can use your electric appliances in India, if the standard voltage in your country is in between 220 – 240 V (as is in the UK, Europe, Australia and most of Asia and Africa).
Which fuel is used in generator?
Regardless of the size, generators may run ongasoline, diesel, natural gas, propane, bio-diesel, water, sewage gas or hydrogen. Most of the smaller units are built to use gasoline(petrol) as a fuel, and the larger ones have various fuel types, including diesel, natural gasand propane (liquid or gas).
When frequency increases what happens to voltage?
The change in frequency can affect the impedence of AC circuit . when we increasethe fc the Xc decreases hence voltage drop across capacitor affected. when we increase frequency then X increases . hence it will affect the voltage drop across inductor.
