Hi I have a question about temperature rise and thermal conductivity. If I have a small 1 watt heater (3 x 3 x 3mm) in the middle of a rectangular block (100x40x70mm) made of a material that has a thermal conductivity of 0.48W/mk, how do I work out the final temperature that the block settles...

Thanks for the reply, Apologies for the delay. I believe this is the spec for the existing GDT, which is across the 100V audio lines. http://www.epcos.com/inf/100/ds/a81a500xx1490.pdf Reading on the epcos website it seems to me that the 3-pin types are more like two separate GDT...

3-pin (Gas Discharge Tube) Surge arrester rating "DC spark over voltage" Could someone please help with a question about Gas Discharge tube, surge arresters rating? I am looking at a public address audio equipment which uses a 100vrms audio lines driven from a audio transformer. Currently...

Hi Thanks for the responses. I have seen several references to the fact that two laser beams will produce interference patterns. I have been trying to find them, one is below. https://www.physicsforums.com/showthread.php?t=218827. When I find another I will add it in. OK, I've done a...

Hi I guess my question is really this, is there an equivalent experiment/or research to the double slit experiment, carried out at Radio frequencies? i.e that radiowaves also travel as a wave but arrive as a particle, and interference can be made to break down when the path of the...

Hi I wonder if I could get help with some questions that have puzzled me related to the two split experiment and electromagnetic interference in general. I know that if you shine a laser beam through the two split experiment then inference patterns will appear, and that if the path of a...

So the electron has an effect on the light source such that it deflects photons towards the detector, so detecting which slit the electron passes. Are there any other ways to detect the passing electron, that don't have any effect on the electron, maybe detecting the electrons magnetic field...

Thanks for the quick reply. I'll go and do some reading.

Hi I would really appreciate if someone could answer what maybe a really simple question. I'm no physics expert but I do read a lot and I have a keen interest. My question is related to light interference and the double slit experiment. I know that by observing which slit a photon of...
