Short answer: why is the higher the current frequency, the greater the effective resistance of the AC transmission line

Because the current flow in the wire increases, the inductance potential also increases, so the loss is large. Just imagine, if the water in the pipe is always in one direction of resistance, or back and forth resistance is big!

The nerve transmits bioelectricity. Why not apply the transmission line theory in electronics, and the human body will not be disturbed by electromagnetic fields?
Like the electronic system, the brain also releases extra electromagnetic radiation when it works, such as brain waves. But compared with the complex electronic system, why is there no EMC problem in the brain? Why is there no crosstalk between nerves? Can such a perfect system be used for reference in the electronic system?

Bioelectricity is the result of ion movement and current is the result of electron movement. The power source of bioelectricity is chemical energy and the power source of current is magnetic field produced by battery or generator. Nerve fibers are wrapped by nerve sheath, which can prevent the free diffusion of ions and ensure the normal change of ion concentration on both sides of nerve fiber

Find the basic law of voltage, current and resistance of series and parallel circuit
For example: u = U1 = U2 = U3. = UN in parallel
I don't know if it's right. There are all the other rules and laws. If it's OK, points will be added
It's a hand fight. It's simple. It's copied. No points

Series circuit:
The current relation is I = I1 = I2 = I3 =. = in
The voltage relation is u = U1 + U2 + U3 +. + UN
The resistance relation is r = R1 + R2 + R3 +. + RN
Parallel circuit:
The current relation is I = I1 + I2 + I3 +. + in
The voltage relation is u = U1 = U2 = U3. = UN
The resistance relation is (1 / R) = (1 / R1) + (1 / r2) + (1 / R3) +. + (1 / RN)

Why does Ohm's law talk about the relationship between current and voltage, the relationship between current and resistance, and why not talk about the relationship between voltage and resistance?
In addition, I read a book and checked a question, saying that there are two birds, one standing at both ends of the bulb, the other standing on the wire, saying that the bird standing on both sides of the bulb can get an electric shock, while the bird standing at both ends of the guide is OK. I think the answer is: there is voltage under the bird standing at both ends of the bulb, So electric shock. Standing under the birds at both ends of the wire, there is no voltage, so no electric shock? Is there no voltage at both ends of the wire? I think if there is current in the wire, there should be voltage. Right? (with batteries in series)

Faint, the first bird standing at both ends of the bulb, of course, there is a current through it, no electric death is strange!
The second bird, just standing on one wire! Usually you look up on the roadside to see where there is a bird standing on two wires? (it may be that its feet are not long enough! Ha ha) standing on only one wire does not mean that there is no current passing through the wire, but it does not form a circuit with the bird, unless it stands on one wire with one foot and the other on the other wire, Then you can eat roast birds! Ha ha! This is the same as the principle of home circuit. The zero line and fire line need to be contacted together before there is current passing through (refers to passing through people)
If you touch zero line and live line at the same time, the voltage will drop from 220 V to 0 V. such a large voltage drop will not kill you?

What is the remainder of 888... 88 divided by 26?
Try to use formulas to solve problems in a primary school way,

Because 888888 / 26 = 34188, that is, every 6 8 can be divided by 26, while 2001 = 6 * 333 + 3
So the number 888... 88 divided by 26 in 2001 is 888 / 26, and the remainder is 4
In 2001, 888... 88 is divided by 26, and the remainder is 4

Simple calculation of 0.45 * (6 11 / 25) + 3.56 / (2 2 / 9)

45 * (6 11 / 25) + 3.56 / (2 2 2 / 9)
=（9/20）*(161/25)+(89/25)*(9/20)
=(9/20)*(161+89)/25
=(9/20)*10
=9/2

Ask (x-c1) 2 + (y-c2) 2 = 1 which is the implicit general solution of the differential equation, where C1 and C2 are arbitrary constants
RT

The two sides are deriving x at the same time
There is x-c1 + (y-c2) y ~ = 0, which is the general solution of the tangent equation of a circle

Given that the system of inequalities x-a ≥ 0 and - 2x ＞ - 4 have solutions, then the value range of a is:

X＜2
A＜X

If (1 + x) n = A0 + a1x + a2x2 + +Anxn (n ∈ n *) and a1 + A2 = 21
A. 15B. 20C. 56D. 70

From a1 + A2 = 21, cN1 + cn2 = 21 {n = 6, so the maximum value of the coefficient is C63 = 20, so B

Short answer: why is the higher the current frequency, the greater the effective resistance of the AC transmission line
