Question

"Сила тока" 4·10 -4 cos 4·10 -6 t "Сила тока "m, "Сила тока "дествующие, w , V , T -???

Answer 1

Уравнение силы тока: i(t)= 4*10^-4*сos4*10^-6*t A, здесь: амплитудное (максимальное ) значение Im=4*10^-4 A, действующее значение I=Im/√2=2.8*10^-4 A, угловая частота w=4*10^-6 рад/сек, частота f=w/2π=4*10^-6/(2*3.14)=0.64*10^-6 Гц, период Т= 1/f=1.57*10^6 ceк

Answer 2

It seems like the provided text is a bit ambiguous and incomplete. However, I will try to interpret and provide some explanations based on what I can understand.

The given expression is:

"Сила тока" = 4·10^(-4) cos(4·10^(-6) t)

Here, "Сила тока" translates to "current" in English. So, the expression represents the current as a function of time (t) in an alternating current (AC) circuit. The current is given by the formula:

Current (I) = 4·10^(-4) cos(4·10^(-6) t)

Let's break down the terms:

1. 4·10^(-4): This is a constant, and it represents the maximum amplitude of the current. The maximum current in the circuit is 4·10^(-4) amperes.

2. cos(4·10^(-6) t): This is a cosine function, where "t" represents time in seconds. The argument of the cosine function (4·10^(-6) t) determines how the current varies with time. The "4·10^(-6)" is a constant, and it represents the angular frequency (ω) of the current.

Now, let's address the other variables mentioned in the question:

• "Сила тока"m: It seems like "Сила тока"m is a mistranslation, but it might be referring to the maximum current (I_m) in the circuit, which we already identified as 4·10^(-4) amperes.

• "Сила тока"дествующие: This term is unclear, and I cannot determine its meaning without additional context or correct translation.

• w: The small letter "w" is not mentioned in the given expression or context. It's possible that "w" is intended to represent angular frequency (ω), which we already identified as 4·10^(-6) rad/s.

• V: The variable "V" is not mentioned in the given expression. Without more information, it's challenging to determine its meaning.

• T: The variable "T" is not present in the expression either. It might be referring to the period of the current, which is the time taken to complete one full cycle of the current waveform. The period (T) is related to the angular frequency (ω) by the formula: T = 2π / ω.

Please provide more context or clarify the missing parts if you want a more detailed explanation or calculations related to the specific variables "V," "T," and "Сила тока"дествующие.
