Answer: A solid-state component with three layers of semiconductors is a transistor.
Step-by-step explanation:
A device with the help of which current or voltage is regulated and for electronic signals it acts as a switch or gate is known as a transistor.
A transistor has three layers of semiconductors. Each of these layers are capable of carrying current.
Thus, we can conclude that a solid-state component with three layers of semiconductors is a transistor.
