The transistor are usually made of

The transistor are usually made of

  • A. metal oxides with high temperature coefficient of resistivity.
  • B. metals with high temperature coefficient of resistivity.
  • C. metals with low temperature coefficient of resistivity.
  • D. semiconducting materials having low temperature coefficient of resistivity.

Step-by-step solution

Transistors are semiconductor devices, typically made from materials like silicon or germanium. Semiconductors have a negative temperature coefficient of resistivity, meaning their resistivity decreases with increasing temperature, which is generally considered a low temperature coefficient compared to metals. Options A, B, and C refer to metal oxides or metals, which are not used for transistors.
