Frequency and Voltage relation

AI Thread Summary
Frequency in electronics refers to the number of cycles of a signal per second, while voltage is the electrical potential difference. Different frequencies can coexist in a single cable, and devices like de-multiplexers or tuned circuits are used to separate these signals based on frequency rather than voltage. Each electromagnetic wave, such as those received by a radio antenna, does not produce a different voltage but is instead distinguished by its frequency. Understanding the relationship between frequency and voltage is crucial, as they operate independently in signal processing. This knowledge is essential for grasping how electronic devices manage multiple signals.

Hi, I'm confused about the meaning of the term frequency used in electronics. I'm not sure if I understand what it means.

For example:

There a number of frequencies travel through a single cable television, at the end point does the de-multiplexer recognizes each signal by its voltages?

E.g. Signal1 at some frequency producing different voltage depending on frequency.

Another example is radio waves received by radio antenna, does each EM wave produce different voltage?

I would like know the relation between frequency and voltage, so i can understand what frequency means in electronics.

No they are independent. The way they separate different frequencies in radio for instance is using a tuned circuit like a narrow band filter. Tuning that to different frequencies separates out each one.
 
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...
