AI Thread Summary
In the discussion about alternating voltage, the peak voltage is identified as 50kV with a frequency of 400 Hz. The equation for the voltage is expressed as V = V₀ sin(ωt). It is clarified that V₀ represents the peak voltage, not the RMS voltage. The RMS voltage can be calculated as V₀ divided by the square root of 2, approximately V₀ x 0.707. Understanding these relationships is essential for working with alternating current systems.

hi, this is probably really obv but say you had an alternating voltage that has peak voltage 50kV and a frequency of 400 hz and you want to write the voltage as V=Vosinwt, how do you work out V0? is it the rms voltage?

cheers

Vo is the peak voltage.
The rms voltage is Vo/√2 [Vo x 0.707 approx]
 

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...
