I studied that model for the transformer in one of the classes of my course, and also briefly studied a procedure to measure experimentally the values of the components in the model, the model is a way of modeling the transformer with basic components, and if you analyze the circuit with that...
I don't think we have met, I just placed this question in the forum for anyone that would like to answer. Is just that you are trying so much to put the source of the voltage in a box so that you can apply Kirchhoff law, so that the voltage drop in two components with the same two terminals is...
Ok, let me explain my problem.

If the circuit is a battery and the resistors(2 cables and the tube), because dB/dt=0, then you can apply Kirshoff law(that is what you get when you put in Farady law dB/dt=0), that says that the sum of the...
Come on, you are running away from the question I made, I don't know the answer but I don't make up messy explanations. And I also don't know if is correct to measure the voltage in a circuit where dB/dt is different from zero with a multimeter. Because of the transformer winding dB/dt is not...
I used a transformer from a microwave because the original primary winding can support large currents, and because it has a large case so I can rewind the secondary with tick multifilar copper wire.
I can read a voltage with the multimeter, just wasn´t sure if the voltage that I am reading is...
Hello, I have the following question, I am trying to build a home made hot air gun for electronics soldering, my approach was with a modified Microwave oven transformer, multifilar 12mmxmm copper cables, and a 15cm stainless steel tube, the air is pumped from a powerful aquarium air pump. The...
Thank you for your explanation and effort. I don't think I'm prepared to understand your favorite explanation, because i am using one of those big physics books that covers a lot of subjects and the chapter about nuclear structure is just an introduction to the subject and so is very simplified...
So, joining rule 1 and 2, you are saying that the total mass of a system isn't just the sum of the individual masses, the total mass of the system is also affected by the potential energy of it's constituents. Is that what i was missing?
Could you explain why that happens?, or possibly, if that...
When i look at E_2 = m_p(c^2) + m_n(c^2) - 40 MeV, I'm interpreting it as: the total energy in situation 2 (particles together) is the energy because of the particles masses(individual mass m_p and m_n) less 40Mev because of their position (they have -40MeV when they are together because of the...
i didn't understood yet
What i didn't understood in your explanation is:
when you sat that E_2=E_1-40MeV, your saying the total energy is E_1 because of the mass of the particles less 40MeV because of their position in space, you also say in the end that the change in the total energy in the...
The two 3ohm resistors aren't connected in parallel, in order to have two resistors in parallel their terminal must be the same, that is they must be connected between the same two nodes. A node is a portion of the circuit were the electric potential is the same everywhere, that is a wire were...
In the book I'm studying, there is a graph for the potential energy of a system made by a free proton and a free neutron, the graph shows that the potential energy of the system as a function of the distance between the particles is zero for large distances, it has a minimum(aprox. -40MeV) at...
Could you explain to me how you passed from dr= \sqrt{\frac{-2C}{mr}+A}dt
to \frac{dt}{\sqrt{\frac{-2C}{mr}+A}}= dt
, when you talk abut integrating the last equation e have no problem integrating the right side, but on the left side there is a dt so the independent variable is t, and I am to...
I’m trying to solve the following problem for a long time:
There are two charged particles, one doesn’t move, the other is being accelerated and is initially at rest, I would use the particle that doesn’t move as the referential, this referential has only one dimension, how do I find the...
