    A question



    Sir What is the use of the transister in this lie detector, although we can simply by aplying votage and using an ohm meter find the resistance of the skin. Then why v use transister in this circuit?

    To give gain and a higher input resistance, you're measuring a fairly high value.

    Those Scientologists are gonna try to sue you now, for exposing the plans to their top-secret "E-Meter".
