The vocal range of a countertenor is equivalent to that of the female contralto or mezzo-soprano voice types. A trained countertenor will typically have a vocal center similar in placement to that of a contralto or mezzo-soprano.
Making the world better, one answer at a time. there are basically two types of conductors. ohmic or linear conductors, non ohmic or non linear conductors. ohmic conductors follow ohms law which is V=IR. In an ohmic conductor current changes linearly with voltage or potential difference across its ends.etals such as copper typify conductors, â¦ while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Conductor implies that the outer electrons of the atoms are loosely bound and free to move through the material.
Examples of Conductors and Insulators Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division. It is more appropriate to think of materials as being placed somewhere along a continuum. Those materials that are super conductive (known as superconductors) would be placed at on end and the least conductive materials (best insulators) would be placed at the other end.
