    Personally, I've never heard of a locus drawing and neither did Wikipedia, however, according to them, Locus is the name of several journals for artists. Also, one definition of locus [or loci] is the set of points satisfying a condition such as a curve; as such it/they would be used in mechanical drafting or drawings. Hope this helps; if not, give Google a try.

    Perhaps you are talking about root locus diagrams. Google "root locus".

    It's all about the poles and zeroes...used in control system stability calculations.

    I too thought root locus diagrams when I first read this question. Its an old, in some practical cases obsolete method, however for learning the rudiments of control system theory it is a good way of cementing the basics.

    locus diagram is presentation of impedance (L(&or)c(&or)R) where the 'R' is on the x axis and the(L,c) are on the y axis and can be used in the presention admittance and using ohms lw we can get the current in a circuit or voltage on that circuit

    Smith charts also serve this function.

    i don't know much about smith charts but i think by locus diagram we can determine the behaviour of the circuit

    Do you care to embellish? This is certainly a different interpretation from those outlined previously, when we talked about the root locus diagram which is essentially a graphical method for ascertaining the location of the closed loop poles of a system without the necessity to compute them explicitly.

    If one of the circuit element is variable , then the characteristics of the circuit varies .The locus of the extremity of current phasor ,obtained for various values of a variable element is called a locus diagram .
