direct electric current การใช้

"' Electro Precipitation "'is the removal of direct electric current ( introduced via parallel plates constructed of various metals that are selected to optimize the removal process ) through contaminated water.
The unit of magnetomotive force is the ampere-turn ( At ), represented by a steady, direct electric current of one ampere flowing in a single-turn loop of electrically conducting material in a vacuum.
By contrast, noninvasive dermal anesthesia can be established in 5 15 min without distorting underlying tissues by lidocaine iontophoresis, where a direct electric current facilitates dermal penetration of positively charged lidocaine molecules when placed under the positive electrode.
The works was supplied with compressed air for pneumatic drilling, riveting, and chipping hammers; a hydraulic plant for the 250-ton plate flanging press and a 20-ton press; and both alternating and direct electric current.
"' Electrokinetics remediation "', also termed "'electrokinetics "', is a technique of using direct electric current to remove organic, inorganic and heavy metal particles from the soil by electric potential.
