I have read in the following article the expression "high breakthrough field": https://link.springer.com/article/10.1557/PROC-871-I9.6
I tried to find out in the internet what is the definition of that and what it refers to in the transistors but I couldn't find anything!
Thank you in advance!
As we know that the magnetic induction causes an electric current in a wire and Faraday has formulated his Electromotive equation ##\epsilon=-\frac{d\Phi}{dt}##. And then Maxwell-Faraday's equation is: ##\nabla \times E=-\frac{\partial B}{\partial t}##, until now this was just an introduction...
Thank you a lot for your comment. Actually I didn't understand what do you mean about counting...? And how did you deduce that from the law number 4 and what does that mean?
Regarding function ##\Phi##, how it stay the same with power 3 (or power 5)?!
I'm reading about the derivation of ampere force law formula, which is $$ F=k_A \iint \frac{i'ds' \times (ids \times \vec{r})}{\vec{r}^2}$$ where K_A is mu_0/4pi. In the article that I read, they have assumed such these paths:
And according to ampere's conclusion that he had from observation...
Thank you so much, now it is more clear for me. And also I added the minus. Maybe just a question regarding the 4pi in the denominator.. does it come from a physical definition or mathematical concept?
We all know that Poissson's equation in electrostatic is:
$$\nabla^2\phi=-\frac{\rho}{\epsilon_0}$$
My question is: why the solution, let's say for 1D, is not just double integral as follows:
$$\phi=\iint -\frac{\rho}{\epsilon_0} d^2x$$
which gives x square relation. But the actual solution...
