Ideas and customs that are current are generally accepted and used by most people. Current thinking suggests that toxins only have a small part to play in the build up of cellulite see also alternating current, direct current. happening or existing now (curant, present participle of courre , from currere). alternating current density current direct current electric current Labrador Current ocean current rip current turbidity current
An electric current is a flow of electricity through a wire or circuit. A powerful electric current is passed through a piece of graphite
A current is a steady and continuous flowing movement of some of the water in a river, lake, or sea. Under normal conditions, the ocean currents of the tropical Pacific travel from east to west The couple were swept away by the strong current
Generally, a horizontal movement of water Currents may be classified as tidal and nontidal Tidal currents are caused by gravitational interactions between the Sun, Moon, and Earth and are part of the same general movement of the sea that is manifested in the vertical rise and fall, called tide Tidal currents are periodic with a net velocity of zero over the particular tidal cycle See tidal wave Nontidal currents include the permanent currents in the general circulatory systems of the sea as well as temporary currents arising from more pronounced meteorological variability Current, however, is also the British equivalent of our nontidal current See total current
The movement of electrical charges in a conductor; carried by electrons in an electronic conductor (electronic current) or by ions in an ionic conductor (ionic current) "By definition" the electrical current always flows from the positive potential end of the conductor toward the negative potential end, independent of the actual direction of motion of the differently charged current carrier (or "charge carrier") particles Two kinds of currents must be distinguished: "direct current (dc)" and "alternating current (ac) " Direct current is the unidirectional continuous flow of current, while alternating current is the oscillating (back and forth) flow of current In electrochemistry, we almost always use direct current Consequently, the term "current" always designates "dc" in this dictionary unless specifically stated to be "ac " The normal household current is an alternating current The measurement unit of current is the ampere
The rate of flow of electricity The movement of electrons along a conductor It is comparable to the flow of a stream of water The unit of measurement is an ampere
The movement of electrons per second through a conductor or a component It is measured in amperes and is designated by the letter, I There are 6 25 x 1018 electrons per second in one ampere (1018 = a billion billion)
