    Help me figure out the resistors needed for my batteries in series setup

    Re: Batterys In Series yup.... methew is right.... u just check with 3 volts , i think it will work..... bye:D

    short and open circuit

    i got the idea for open circuit......... but how we check short circuit?... it should be in automatic sense.....:idea: i need some clear explanation

    short and open circuit

    suppose i have "n" number of wire and all are independent to each other which connected to other terminals........ my problem is " if any short or open circuit occur among the wires, HOW WILL WE CHECK THAT?????? just by glowing of DIFFERENT colour of LED like RED...

    Schmitt trigger circuit

    hi for designing a schmitt trigger circuit for desired levels......., first change the magnitude of sign wave with adding some dc components to that......then u can get 5V and 0V ....... but first u check it in software circuit design then go for the original one..........:|

    How to design a bandpass active filter?

    Re: Filter Design hey..... u want to design a filter its not clear that whether it is active or passive but if u want to make it more responssive ....u use active one and make it with Op-amps...and check the phase margin and magnitude one with Bode plot of filter and check whether it is...

    Negative Frequency - What is it?

    hi........... the -ve frequency just show symmetry ............ and the easyness of the problem.........it has no physical significanse............ u can start it zero.........but at that time ur calculation is complex but u will get the same result......... that's why we go for -ve frequency...

    Looking for elementary books on Electromagnetics

    Re: Electromagnetics hi........... when we apply voltage or anything which generate current ......... the wire electron gets excited by electric field of source........and as we know there is overlapping between conduction band and valence band so there is high number of free electron...

    Why the power mosfet in this circuit blow-up?

    ya........ wat my friend PAULHOLLAND told is right .......... we will use capacitor to control the current flow.......... but the fact is that at t=0, capacitor work like a short circuit ........... After this the circuit will work or not?

    Why the power mosfet in this circuit blow-up?

    hi............. its because of high current at the start of operation which the MOSFET can not withstand:?:

    behaviour if roots are in poles

    hi....... along with stability, pole of a closed loop system or charecteristics equation shows how much our system close to instability.............:idea:
