Which is not a semiconductor?

Question

transistor
integrated circuit
transformer
diode

Answer 1

Transformer is not a semiconductor. Transformers are made of insulated wire wrapped around a magnetic core, and they are used to transfer electrical energy from one circuit to another through electromagnetic induction. Semiconductors, on the other hand, are materials that have electrical conductivity between that of a conductor and an insulator, and they are used extensively in electronic devices like diodes, transistors, and integrated circuits.
