AI Thread Summary
Photo-conductive and photo-voltaic devices both rely on light intensity and involve the movement of charge carriers. The key difference lies in their functions: photo-conductive devices alter their conductivity in response to light exposure, while photo-voltaic devices generate electrical power through voltage induced by electromagnetic radiation. This distinction clarifies the operational principles of each device. Understanding these differences is crucial for applications in electronics and renewable energy. Overall, recognizing how each device interacts with light is essential for their effective use.

I am geting confused ( :confused: ) that what is the difference between photo-conductive and photo-voltic devices.

as boath devices depends on the intensity of light, boath depends on no of charge cariers,...
In boath cases there is movement of charge cariers , so there is a flow of current, then what is the difference :(
 
Physics news on Phys.org
Imho the difference you are looking for is that photoconductive devices only change their conductivity when exposed to light while photovoltaics actually generate electrical power by the means of voltage induced by EMR.
 
hmmmm thanks , its looking right ans thanks , :)
 

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...
