Concept explainers

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

按ESC | 即可退出全屏模式 Gas insulation is important for transmission lines, outdoor insulators and Gas-insulated- Substations (GIS). Understanding the breakdown mechanisms and behaviour of insulation materials is key to the optimum design of insulation systems. The speed distribution function of electrons in a gas containing electrons, ions and atoms is controlled by the electric field strength, E, and can be expressed as fo (E, v). It satisfies the relationship of (E, v) dv=1. i) ii) Convert the above electron speed distribution function into an electron energy distribution function that satisfies the relationship f(E, ɛ) dɛ =1 where & is the electron energy and ƒ(E, ɛ) the electron energy distribution function. The electron number density is ne and the atom number density is na in the gas. The ionisation cross section of the atoms by electron impact is a function of electron energy, ɛ, and can be written as σ¡ (ɛ). Similarly, the attachment collision cross section between an electron and an…
