Addition of electrically conductive particles can yield conductive hot-melt formulations. The process is useful for applying materials to any electrically conductive surface. Its use is limited to electrically conductive materials. Thermal runaway is more typical of electrically conductive liquids such as salty water. Faraday's law is used for measuring the flow of electrically conductive liquids and slurries. Semiconductor lasers are diodes which are electrically pumped. Atomically thin boron nitride is one of the strongest electrically insulating materials. Sadoway, uses molten alloys of magnesium and antimony separated by an electrically insulating molten salt. "m"CVT is a variable magnetic transmission which gives an electrically controllable gear ratio. Photons are viewed as the carriers of the electromagnetic interaction between electrically charged elementary particles. A relay is an electrically operated switch. A TRIAC resembles an SCR in that both act as electrically controlled switches. Thus, molecules exist as electrically neutral units, unlike ions. It is sandwiched between two electrically conducting plates. Leather trimmed sports seats were fitted together with electric windows and electrically adjustable heated mirrors.
