In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Read moreWhat is frequency Byjus?
Frequency is the number of waves that pass through a point in a given period of time . Frequency of the wave is inversely proportional to the time period. Therefore, the frequency can be defined as the number of times the motion repeats itself in one second.
Read moreWhat is frequency class 9th?
Frequency. The number of vibrations per second is called frequency. The SI unit of frequency is hertz (Hz).
Read moreWhat is mean by frequency in electrical?
Electrical frequency is the measure of the rate of that oscillation and is measured in the number of changes per second – also called hertz (Hz). A generator running at 3,000 rpm, with two magnetic poles, produces electricity at a frequency of 50Hz.
Read moreHow can we define frequency?
frequency, in physics, the number of waves that pass a fixed point in unit time ; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Read moreWhat is the meaning of frequency of voltage?
Frequency is the number of cycles that a voltage waveform repeats itself per seconds . A voltage with 0 frequency in effect is steady at a certain value which is also known as DC voltage.
Read moreWhat is frequency used for in electronics?
In electrical engineering, the term frequency is used to denote the number of cycles per second of alternating current (a.c) . The value of voltage in a.c. varies with time, at a fixed rate. For example, at 50 Hz, the voltage increases from zero to Vmax and then reduces way down to -Vmax, 50 times per second.7 Ağu 2017
