so biasing only helps to improve the reverse current ...?? if it is so...can we get the reverse current flow through the load and produce potential difference across it without biasing the diode...??
so if we operate it in forward bias...the depletion layer length would be less compared to that as in reverse biased condition...there by reducing its sensitivity . why only the depletion layer is exposed to light... not all the device..?
why photodiode is operated in reverse bias??
can anyone please explain why photodiode is operated only in reverse bias?? can we operate it forward bias state also??
does this mean that our heart rate would slow down...and all our body functions also slow down...if we were traveling at 90% of c so that our age doesn't increase compared to the person on the earth?
i think in case of light ..,we feel electromagnetic radiation...not electromagnetic field...we cannot feel the electromagnetic field of an electromagnet...but we can see the effect of its presence on other substances..
the presence of the charged particle can be replaced by its field...refer feynman lectures on physics chapter 2 vol 1...in case of light...it is electromagnetic radiation...it is that radiation we feel...not electromagnetic field..we cannot feel electric and magnetic fields..can we??
i think that fields don't exist...these are just lines that tells us the force direction at various locations surrounding the charge...those are nothing but "effect" from the cause "turning on" of the charge..there would be no effect on the cause that produced the effect
i want to ask one more doubt...,please spare me...you said that there are two effects traveling opposite to one another...nearly at c...,then what would be their relative speed with respect one another??
