Thanks, I am familiar with Kirchhoff's Circuit Law, just not with the abbreviation. I solved that exercise for the case of identical capacities, but I was wondering how to do it for different ones. The wye to delta transformation is the way to go. (I did not know of that before). For DC the...

Thank you for the hint with wye to delta conversion. I have just read about it how to do it for resistances, I assume it will be similar done with the impedance of capacitors...will this be still correct for DC? What are the KLC equations ?

Thank you for your response, but it is not that simple. Please take a closer look at the capacitor number 6: if it would not be for it, the network would be easily solveable as you wrote, but that is not the case, or I fail to see how one can redraw the network in a simpler way. I do know how to...

Homework Statement I would like to know how to calculate the total capacity of the capacity network displayed in the uploaded picture. I know how to calculate the total capacity if the capacity are in parallel or in series, but I am confused by the capacity Nr 6. I know how to calculate the...

[Moderator's Note: This post and the following four have been merged into this thread.] Why does the antiparticle go forward in time? According to the Feyman-Stückelberg equation, one can either speak of a positive energy particle going backwards in time or a negative energy particle (its'...

E.g. wikipedia, respectively: https://en.wikipedia.org/wiki/Negative_energy?wprov=sfla1, https://en.wikipedia.org/wiki/Negative_mass?wprov=sfla1 and https://en.wikipedia.org/wiki/Antiparticle?wprov=sfla1.

What is the relationship between negative energy, negative mass and antiparticles? I have read some articles but I am still confused. Does negative mass exist? Does negative energy exist with the exception of the Kasimir effect which I understand. Are antiparticles really only the negatice...
