2. Control grid - Wikipedia

   en.wikipedia.org/wiki/Control_grid

   A less negative, or positive, voltage on the grid will allow more electrons through, increasing the anode current. A given change in grid voltage causes a proportional change in plate current, so if a time-varying voltage is applied to the grid, the plate current waveform will be a copy of the applied grid voltage.

3. Electricity - Wikipedia

   en.wikipedia.org/wiki/Electricity

   The positive-to-negative convention is widely used to simplify this situation. An electric arc provides an energetic demonstration of electric current. The process by which electric current passes through a material is termed electrical conduction , and its nature varies with that of the charged particles and the material through which they are ...

4. Gridded ion thruster - Wikipedia

   en.wikipedia.org/wiki/Gridded_ion_thruster

   The negative voltage of the accelerator grid prevents electrons of the beam plasma outside the thruster from streaming back to the discharge plasma. This can fail due to insufficient negative potential in the grid, which is a common ending for ion thrusters' operational life.

5. Electrical grid - Wikipedia

   en.wikipedia.org/wiki/Electrical_grid

   One conceptual plan of a super grid linking renewable sources across North Africa, the Middle East and Europe. [18] A super grid or supergrid is a wide-area transmission network that is intended to make possible the trade of high volumes of electricity across great distances. It is sometimes also referred to as a mega grid.

6. Electric power - Wikipedia

   en.wikipedia.org/wiki/Electric_power

   Electric power flowing out of a circuit into a component is arbitrarily defined to have a positive sign, while power flowing into a circuit from a component is defined to have a negative sign. Thus passive components have positive power consumption, while power sources have negative power consumption. This is called the passive sign convention.

7. Cathode bias - Wikipedia

   en.wikipedia.org/wiki/Cathode_bias

   The grid circuit puts the grid at zero volts dc relative to negative side of the plate voltage supply, causing the grid voltage to be negative with respect to the cathode by the required amount. [3] Directly heated cathode circuits connect the cathode bias resistor to the center tap of the filament transformer secondary or to the center tap of ...

8. Magnetic declination - Wikipedia

   en.wikipedia.org/wiki/Magnetic_declination

   The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation." [1] By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west.

9. North American power transmission grid - Wikipedia

   en.wikipedia.org/wiki/North_American_power...

   The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.
