Definitions:

Ohmic Value

The resistance value of a component or material, typically measured in Ohms (Ω), indicating how much it resists the flow of electric current.

Fixed

In an electrical or mechanical context, "fixed" typically refers to components that are stationary, unchanging, or permanently set in a particular configuration.

Voltage Dividers

Circuits that reduce voltage to a lower value, using a series connection of resistors or other components to distribute the input voltage into smaller outputs.

Field-Effect Transistors

Semiconductor devices used to control the electrical behavior in circuits, relying on an electric field to control the flow of current.
