Answer:
The value is
Explanation:
From the question we are told that
The maximized electric field strength is ![E = 3.0 \ MV/m = 3.0 *10^{6} \ V/m](https://tex.z-dn.net/?f=E%20%3D%20%203.0%20%5C%20MV%2Fm%20%3D%203.0%20%2A10%5E%7B6%7D%20%5C%20%20V%2Fm)
The diameter is ![d = 1.5\ cm = 0.015 \ m](https://tex.z-dn.net/?f=d%20%3D%20%201.5%5C%20cm%20%20%3D%20%200.015%20%5C%20%20m)
Generally the cross -sectional area is mathematically represented as
=> ![A = \frac{\pi * d^2 }{4}](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B%5Cpi%20%2A%20d%5E2%20%7D%7B4%7D)
=> ![A = \frac{3.142 * 0.015^2 }{4}](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B3.142%20%20%2A%200.015%5E2%20%7D%7B4%7D)
=> ![A = 0.0001767 \ m^2](https://tex.z-dn.net/?f=A%20%3D%200.0001767%20%5C%20%20m%5E2)
Generally the maximum power is mathematically represented as
Here c is the speed of light with value ![c = 3.0 *10^{8} \ m/s](https://tex.z-dn.net/?f=c%20%3D%20%203.0%20%2A10%5E%7B8%7D%20%5C%20%20m%2Fs)
is the permeability of free space with value ![\mu_o = 4 \pi *10^{-7} \ H/m](https://tex.z-dn.net/?f=%5Cmu_o%20%20%3D%204%20%5Cpi%20%2A10%5E%7B-7%7D%20%5C%20%20H%2Fm)
=>
To develop this problem it is necessary to have the concepts related to Ohm's law and resistivity.
Ohm's law is defined by the equation
![V= RI](https://tex.z-dn.net/?f=V%3D%20RI)
Where
R=Resistence
I = current
V= Voltage
While the resistivity equation is given by
![\rho= R*\frac{A}{L}](https://tex.z-dn.net/?f=%5Crho%3D%20R%2A%5Cfrac%7BA%7D%7BL%7D)
Where
resistivity
A= cross-section area
R= Resistance
L=Lenght of wire
A) We can find the resistence re-arranging our first equation, so
![R= \frac{V}{I}](https://tex.z-dn.net/?f=R%3D%20%5Cfrac%7BV%7D%7BI%7D)
![R= \frac{120V}{9.85A}](https://tex.z-dn.net/?f=R%3D%20%5Cfrac%7B120V%7D%7B9.85A%7D)
![R= 12.18\Omega](https://tex.z-dn.net/?f=R%3D%2012.18%5COmega)
B) From our second equation we can re-arrange for L, so
![\rho= R*\frac{A}{L}](https://tex.z-dn.net/?f=%5Crho%3D%20R%2A%5Cfrac%7BA%7D%7BL%7D)
![L=\frac{R\pi r^2}{\rho}](https://tex.z-dn.net/?f=L%3D%5Cfrac%7BR%5Cpi%20r%5E2%7D%7B%5Crho%7D)
![L = \frac{(12.18)(3.70*10^{-3})^2(\pi)}{1.5*10^{-6}}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B%2812.18%29%283.70%2A10%5E%7B-3%7D%29%5E2%28%5Cpi%29%7D%7B1.5%2A10%5E%7B-6%7D%7D)
![L=349.34m](https://tex.z-dn.net/?f=L%3D349.34m)
