Tiếng ViệtIn physics and equations of fluctuating values of current and voltage, we often focus on current and potential difference, but in the equation for calculating current and voltage, there is a related value that is corner frequency. What is the frequency? The angular frequency is usually not well known, but the angular frequency can be calculated from the frequency (f) or period (T). TTTT Global will provide you with basic information about angular frequency unit.

What is the angular frequency ?
What is the frequency? In engineering and physics, the angular frequency of a circular motion is a quantity measured by the angle the radius sweeps in a unit of time. It is also considered to be the radio magnitude of the angular velocity vector. Angular frequency has the opposite unit of time.
Frequency TTTT corner can be understood as a multiple of the frequency. It is used in place of frequency to avoid the occurrence of many Pi, in fields that involve a lot of rotation and oscillation such as quantum mechanics and electromechanical mechanics.
Electrodynamics is a fundamental theory of physics that describes the physical properties of nature at the atomic or atomic or subatomic particle level.
Quantum mechanics is a theory that fairly accurately describes electromagnetic phenomena at the macroscopic level, that is, involving large enough spaces that the effects of quantum mechanics can be ignored.

Formula for angular frequency and units of angular frequency
One revolution is 2 Pi rad, which is the angular speed multiplied by the time it takes to complete one revolution. The angular frequency depends only on the time origin. In the equation amperage (i) and potential difference (u) angular frequency.
The formula for calculating angular frequency usually uses the following two methods:
Once you have the value of the period (T) then the angular frequency is equal to 2 times Pi and divided by the period (T).
Once you have the value of frequency (f) then the angular frequency is equal to 2 times Pi and multiplied by frequency (f).
The unit of angular frequency is rad/s, commonly read as radians per second.
With the unit rad is calculated by 2pi rad equals 360 degrees. So 1 rad equals 180 degrees of acidity for Pi.
Equation of current
i = Io x cos( t + initial phase of current)
Where i is the instantaneous value of the current (A)
Io is the maximum value of the current (A)
ω is the angular frequency.
t is time which would normally be the key variable in the equation.
Alternatively the equation can be calculated as i = root 2 x I x cos( t + initial phase of current)
Where I is the r.m.s. value of the current.
Equation of voltage
u = Uo x cos( t + initial phase of voltage)
Where u is the instantaneous value of the voltage (V)
Uo is the maximum value of the voltage (V)
ω is the angular frequency.
t is time which would normally be the key variable in the equation.
Alternatively the equation can be calculated as u = root 2 x U x cos( ωt + initial phase of voltage)
Where U is the r.m.s. value of the voltage.
