AI Thread Summary

AC supply cannot be obtained from a DC transformer, as transformers are designed to operate only with alternating current (AC). To convert DC to AC, additional equipment like an inverter is required. Understanding the fundamentals of electricity is crucial before attempting any modifications or experiments, as improper handling can be dangerous. Safety precautions and knowledge of electrical systems are essential to prevent serious accidents. Proper education on electrical principles is highly recommended before proceeding with any electrical projects.

Can Anyone Just tell How to get a AC supply from a DC transformer by using anything
??

You do not use transformers with DC they only work on AC.
You need to understand a LOT more about electricity before you start mucking about with it otherwise it will kill you.

Thread 'Free surface problem in electrohydrodynamics'

I'm thinking about the following problem. I have an electrified fluid with a constant charge density, Q, within the fluid. Will this necessarily yield a surface charge? Would I have to compute it by looking at the displacement fields on either side of the interface? Would it change if the bulk charge within the fluid remains constant?

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
