    DIODE QUERY

    hi audioguru! even if we consider a diode as a capacitor in this reference ,what happens when we short circuit the ends of a capacitor? will it not get discharged?why wont the electrons on n side move to holes on p side through the external wire?

    DIODE QUERY

    HI. My question is i have an open diode (not in any circuit) .I short its two terminals . Will the current flow through the wire for first few nano seconds to equalize p and n carriers?

    DIODE QUERY

    hi.so what is the conclusion? will the current flow through the short?if yes ,the diode will get depleted of its charge carriers and it will be destroyed .no? what do u think?

    DIODE QUERY

    Hi all. I want to know ,what will happen if we short the 2 terminals of a diode? will the current flow? what i suspect: Current will flow for some time till charge concentrations equate and diode is destroyed ..... i.e its functionality gets over....

    50Hz when you touch Oscilloscope probe

    no audioguru, i think u did not get my question .my question was does our body pick up only 50 Hz or any frequency signal by which it is surrounded say even a 30 Hz or 100Hz . in other words ,, is our body an antenna tuned at 50Hz or does it get automatically tuned to any frequency around it?

    50Hz when you touch Oscilloscope probe

    hi audioguru , thats a strange thing u told.in india we have mains frequency as 50 Hz .Does our body pick only 50 Hz ? If i am in a country with 30 Hz mains frequency and there i touch a CRO with a fan blowing over me ,what will i get on screen? 30 Hz or nothing? In other words, is our body...

    special Switch

    in case your application demands a switch on for some time and off for some time why dont you go for a simple clock type ? u can control the duty cycle as well as the timpe period as per your need. any problem with that?

    Battery current

    hi audioguru! as of what i know till now is that any source can give any current depending on the resistance .what r ur views? but ofcourse too much current causes it to cross rated power and burns it off! am i correct? in short ...are voltage sources current rated or voltage rated?

    Need help to ID some of my components

    indeed 6552 is a regulator .capacitors also r of many types .some are electrolytic (with polarity) while some are ceramic . resistors also of different makes. so cant say without seeing them

    Where's the internal speaker of a computer located?

    it depends on the PC configuration and the manufacturer.Laptos have it on the board itself. while desktops have it (some ) on their sound cards while some have separate!

    3 Minute Timer

    hi. how about using a charging RC circuit so that capacitor voltage builds upto 0.7V in 3 mins .this can be fed to the base of a transistor and push it in saturation. your views ????

    How to derive ohms law

    indeed u can derive ohms law. it comes basically from charge carriers and mobility definition. mobility =speed/Electric field.. speed =distance /time and field = Electric field / distance hence derived .name the constant as R moreover ur definition of law is not correct.it does not say V=IR...
