    CLIPPER CIRCUIT to clip of higher voltages without bias

    http://www.circuitstoday.com/wp-content/uploads/2009/10/Biased-Positive-Clipper.jpg I meant as per the diagram we use a dc supply to clip at higher levels. Is there a way to clip at higher level say 3.5V without using the dc supply?

    CLIPPER CIRCUIT to clip of higher voltages without bias

    Good Day everyone. Is it possible to design a clipper circuit to bias at higher voltage level without using bias voltage? For example. to clip at 3.5V for a input signal of 10V sine without using a BIAS VOLTAGE??

    Number of pi electon

    Oh Borek Sir I didn't mean to say that...!!! Very Sorry Sir :( One double bond is equivalent to 2 pi electrons so 3[double bonds]*2[electrons] = 6 pi electrons

    Complaint PF has guidelines on religion?

    Yeah you are absolutely right..!

    Word problem.

    yeah...Mark Sir is correct.... Eqn(1) y=kx3/y2 Eqn(2) y'=k(76.7)3/(145.5)2 Eqn(2)/Eqn(1)=> y'=21.37y

    Oops...Sorry Sir.... its 76.7...

    Word problem.

    x decreases BY 23.3% means x=100-23.3=76.6% So you have to sub. x=76.6. But if they had given decreases to 23.3% then x=23.3 z=145.5 substituting this in the equation with k=1 we get x=21.37 in the answer which you have mentioned they have divided it by 100...

    Why is earth considered to have zero potential potential energy

    It is very much relative na Sir?
  17. R

    Why is earth considered to have zero potential potential energy

    no I'm asking for earth.what will be earth's actual value of potential energy?
  18. R

    Why is earth considered to have zero potential potential energy

    yes Sir but if we forget and try to calculate earths potential what will be its value?
  19. R

    Why is earth considered to have zero potential potential energy

    ok so P.E. of earth is takes to be 0 for convenience sake correct Sir?
  20. R

    Are potential energy and gravitational potential energy same?

    So Sir you mean to tell that gravitational potential energy and potential energy are proportional to each other?
  21. R

    Why is earth considered to have zero potential potential energy

    Potential energy=Hidden energy!
  22. R

    Why is earth considered to have zero potential potential energy

    But Sir potential energy means internal energy na?
  23. R

    Why is earth considered to have zero potential potential energy

    But what if we choose the earth's potential as infinity? then the potential diffeerence won't be same na!?!
