Electronics

It is the science that deals with the study, design, and application of devices and systems that operate by controlling the flow of electrons or other charged carriers.

A ____ is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.

A ____ is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
