1. 1

    The anode is one of the two ends of a battery or electrolytic cell — the electrode where the material is oxidised, the end that gives electrons out into the wire. Its sister is the , which takes electrons in.

    The anode is one of the two ends of a battery or electrolytic cellanode 是電池或電解槽兩端其中一端——the electrode where the material is oxidised是材料發生氧化反應的那個電極,the end that gives electrons out into the wire也就是把電子送出去到電線裡的那一端。Its sister is the cathode它的另一半是 cathode(陰極),which takes electrons in負責把電子接收進來。

    School pictures often print a plus sign on the anode, and that tidy picture is true in some setups, especially when you are driving electricity through a liquid to split it. Inside an ordinary battery that is lighting a bulb, though, the anode is the minus end. So “anode” and “+” are not married for life; the sign depends on whether the cell is making electricity or using it.

    School pictures often print a plus sign on the anode學校的圖常常在 anode 上印一個正號,and that tidy picture is true in some setups這個簡單的圖在某些情況下是對的,especially when you are driving electricity through a liquid to split it尤其是你通電讓液體分解的時候。Inside an ordinary battery that is lighting a bulb, though但在一顆點亮燈泡的普通電池裡,the anode is the minus endanode 是負極。So "anode" and "+" are not married for life所以 "anode" 跟 "+" 並不是綁死的;the sign depends on whether the cell is making electricity or using it正負號要看這個電池是在「產生」電還是在「使用」電。

    The names were coined in 1834 (Whewell for Faraday) from Greek for “way up,” following an old picture of which way current goes — which is why the signs feel the wrong way round if you think in electrons.

    The names were coined in 1834 (Whewell for Faraday)這些名稱是1834年由 Whewell 幫 Faraday 造出來的,from Greek for "way up,"來自希臘文「向上的路」的意思,following an old picture of which way current goes跟隨的是舊時對電流方向的想像——which is why the signs feel the wrong way round if you think in electrons這也是為什麼如果你用電子的方向去想,正負號會覺得反過來。

    You meet the word in science class, batteries, and , not in ordinary talk.

    You meet the word in science class, batteries, and electroplating你會在自然課、電池和電鍍相關的內容裡遇到這個字,not in ordinary talk日常對話裡不會用到。

anodenoun/ˈæn.əʊd/

  • 1

    businesselectrical-engineeringelectricityAn electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows inwards (and thus, electrons flow outwards). It can have either a positive or a negative voltage with respect to cathode of the same polarized device (depending on whether the device is a load or a source, respectively).

  • 2

    chemistrynatural-sciencesphysical-sciences(by extension) The electrode at which chemical oxidation of anions takes place, usually resulting in the erosion of metal from the electrode.

  • 3

    businesselectrical-engineeringelectricityThe electrode which collects electrons emitted by the cathode in a vacuum tube or gas-filled tube.

  • 4

    businesselectrical-engineeringelectricityThat electrode of a semiconductor device which is connected to the p-type material of a p-n junction.
