Engineering AllOther (1379) According to Shockley equation, the I – V characteristic of a diode is approximated by I = IS [ exp (nVD / VT) – 1 ]. For silicon, let the reverse bias saturation current IS as 0.000000000001. If n is ideality factor with value of 1.5, VT as thermal voltage drop of 0.026 V at room temperature, what is the value of current I that passes through the silicon diode in the heater of evaporator when the forward voltage drop VD = 0.026 V? Please take note that exp is the exponential function with e(1) = 2.718, e(2) = 7.389.
1 2875I am a new valuaer. I am seeking for instruments which r used to locate the site and from where I got it?
Fast,
1 2835Distribution transformer we provided 2 separate earthing pit for Body and 2 separate earthing pit for neutral,we can not connect separate body earthing pit to other earthing pit but we do metal glanding in secondary side cable termination in both side, transformer and PCC panel (LT Panel), is this safe for transformer and other equipment?
1752hi .. i have done my b.e in under electronics and communication engineering and now i have opted for computer engineering which has most of communication related subjects. still what should i answer, if i am been asked "why didnt yu opt for electrical engineering"

We are having proplem with the persperation smell in ETT/ECHO room in our cardiac hospital.The 2 Ton of AC is not conditioning the environment. We have to use exhaust fan to through out of the room bad air. Could anyone suggest how to coup with this effectively using chemical engineering. Any permanent solution to neutralise the bad smell.The Air freshners are not doing enough instead making a bad odour.

how to find 5 kilo meter long under ground 33 kv cable fault location if IR VALUE shows 0.05 M ohm @5000 volt.and cable fault locator shows some time fault distance 3 kilo meter ,3.7 kilo meter and some time 1 kilo meter? now how to find the fault location that where is leakage. note--it is tested with 5000 kv megger and insulation resistance is 0.05 M ohm. and some time 0.03 M ohm comes.
