    Half Comes From Where? Exploring the Origins of 1/2

    i tried a lot but answer goes wrong.. i didn't touched with calculus since long time...May be it is because of this... For the integral of 1+cos(2t) gives 2T+sin(2T).

    Function of enable input in gates

    when the enable is at low the gate/I.C will be disable and when the enable is at high the gate/IC will be disable...but told that To allow input pulses to pass from input to output of the gate, then the "enable" input has to be low...what is correct..if you have any external link about it then...

    Function of enable input in gates

    what are the function of enable input in gates? If in or gate we use it and it is at high and the other two inputs are at low then what will be out put...1/0? Please clear me about the enable input

    Perpetual machine by using free energy of magnets Possible?

    Does magnets posses free energy? Does the machine shown in image will run? If no...give reason... I know it seems to voilate 1st law of thermodaynamics...But why it voilates it?

    A+2b=2a+b=>1=2. please tell me what is the problem

    if we get: a+2b=2a+b =>a-b=2a-2b =>a-b=2(a-b) =>1=2 I can't figure out the problem in it..please tell me

    What is the error in this mathematical proof?

    I got this question from my friend and he solve it like this: 100-100 10^2-10^2 (10-10)(10+10) (10+10) ----------- = -------------= --------------- = ----------- =2 100-100 10(10-10) 10(10-10) 10 Please...

    RC constant of capacitor in RC circuit as a filter

    From the book of Electronic devices by thomas L-Floyd i attached a RC filter circuit here.. What i understand there is the point that in charging there is no resistance to the current coming into capacitor so it will charge instantly or take a little time because of the resistance of diode.and...

    RC constant of capacitor in RC circuit as a filter

    We know that for RC circuit as filter or in multiplier we use capacitors having larger RC constant than the period of input signal.but I am confused here: As long as i know the charging and discharging period of a capacitor are equal wether it is fully charged or not...(tell me i am right or...

    How may signals travel through a cable without interfernce?

    I am an Electrical Engineering.I want to ask that how different signals move in a cable without effecting each other..e.g interference etc.. I am not strictly speaking about it interfence but how at the end we can differentiate these signals and get one of our need.
