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.
Types of transistor. There are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols. The letters refer to the layers of semiconductor material used to make the transistor. Most transistors used today are NPN because this is the easiest type to make from silicon.here are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols.
