EVERYDAY SCIENCE

Detailed explanation-1: -The correct option is D electric current. Electric current is the flow of negative charges called electrons.

Detailed explanation-2: -Electronics is a branch of physics focused on the design of circuits and the study of electrons under various conditions. Electrical engineers oversee the design, testing, manufacturing, construction, and monitoring of electrical and electronic devices, machinery, and systems.

Detailed explanation-3: -An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound).

Detailed explanation-4: -A semiconductor substance lies between the conductor and insulator. It controls and manages the flow of electric current in electronic equipment and devices. As a result, it is a popular component of electronic chips made for computing components and a variety of electronic devices, including solid-state storage.
