Circuitry associated with or involving high-voltage switchgear, step-down transformers, voltage dividers, and other related equipment used to receive high-voltage electricity from a primary source and redistribute or route it at lower voltages to substations or other points of applications.

1. An action that describes the electron density in phase space (a spectral representation of physical space).
2. A function that produces the number of electrons per unit volume of phase space.

1. A curved line on a graph that shows the electron distribution in a solid at different energy levels.
2. A curve or line indicating the electron distribution in the different available energy levels of a solid substance.

The physical character and distribution of natural resources on the face of the Earth: The fundamental differences between land and ocean, latitudinal differences in insulation, spatial variations in receipts of precipitation, and patterns of geological composition and deformation of the Earth's crust together provide the basis for the geographical distribution of resources which distinguish definite geographical patterns of resource availability throughout the world.

The frequency of occurrence of a given series of data for each change in an independent variable; usually represented by a bell-shaped curve: The professor, Dr. Dean, used the concept of normal distribution when calculating the grades for her students.

When compared to students in other universities, the normal distribution of grades in English classes for Susan and the other students at the local university was favorable.
