[amp_mcq option1=”Plastic” option2=”Aluminium” option3=”Wood” option4=”Germanium” correct=”option4″]
The correct answer is (d), Germanium.
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. Semiconductors are used to make a wide variety of electronic devices, including transistors, diodes, and integrated circuits.
Plastic is an insulator. It does not conduct electricity.
Aluminium is a conductor. It conducts electricity very well.
Wood is an insulator. It does not conduct electricity.
Germanium is a semiconductor. It has electrical conductivity between that of a conductor and an insulator.
