關鍵區別-傳導與感應
傳導和感應的關鍵區別在於,在傳導中,能量是通過使用物質來傳遞的,而在感應中,不需要任何介質或接觸來傳遞能量。
什麼是傳導(conduction)?
傳導是以熱或電的形式傳遞能量的過程。在熱傳導中,介質中的原子振動並傳遞熱量,換句話說,熱能。在熱傳導中,介質中的原子通過振動主動傳遞能量。只要存在溫度梯度,熱能就在原子間流動。大多數好的熱導體是固體。它們緊密堆積的結構有助於固體成為有效的導體。但應注意的是,並非所有固體都是好的導熱體。傳導是傳熱的一種方式,熱可以通過對流和輻射來傳遞。記住,我們只加熱鍋的外部,而不是內部。鍋上任何好吃的東西都可以煮熟,因為熱量是通過傳導從火焰傳導到食物上的。
Charge carriers play an important role electric conduction. A potential difference which is bridged by a conductor is also required to implement conduction. Metals are usually good electric conductors since they have delocalized electr*** that can flow and carry the current. Soluti*** such as acids have i*** which are free to employ as charged carriers. Therefore, acidic soluti*** act as electric conductors. Pure water does not conduct electricity, but fresh water can conduct electricity since fresh water contains a **all quantity of i***.
什麼是歸納(induction)?
歸納法這一術語通常被稱為定向。根據字典,定向是指自己或一個人的想法對周圍環境或環境的調整或調整。顯然,雙方應該參與一個定向過程。同樣,在一個誘導過程中,一個必須根據另一個來調整它的質量。
在物理學中,感應分為靜電感應和電磁感應。靜電感應是一個物體在外部電荷存在時產生的靜電電荷的轉化。考慮一箇中性的金屬球體。如果一根帶電的棒靠近球體,中性原子就會電離並分裂成兩部分。然後相似的電荷會互相排斥,形成如下的電荷幾何結構。在這個過程中,杆和球體之間不需要接觸。這種分裂純粹是靜電感應的結果。邁克爾·法拉第因為發現了電磁感應而獲得了榮譽。電磁感應是由時變磁場引起的。通過改變導體周圍的磁場,可以在導體上產生電動勢。此過程不需要聯繫。電動勢完全由電磁感應產生。
Electrostatic precipitators actively employ the concept of electrostatic induction to remove particles from industrial soot. The transformer is incorporated as a major component, from power stati*** to home appliances, It is used to increase the voltage as well as decrease the voltage. Power stati*** usually have step-up transformers to increase the voltage and feed to the tran**ission line, then there may be several points in the tran**ission line to step-down the voltage to a safe level to c***ume by home appliances. The most important thing about the transformer is that it has no direct coupling between the input (primary) and output (secondary), but transfers energy from primary to secondary. Relatively new application of electromagnetic induction is the induction cooker. It’s a soot-free, handy kitchen appliance.
傳導(conduction)和歸納(induction)的區別
傳導和感應的定義
傳導:傳導是熱能通過相鄰分子之間的碰撞傳遞的過程。
感應:感應是電能從一個物體轉移到另一個物體而不接觸物體的過程。
傳導和感應特性
能量轉移
傳導:傳導是利用物質傳遞能量的一種方式。
感應:感應不需要介質或接觸來傳遞能量。
過程
傳導:傳導通路斷開時,傳導停止。
誘導:當雙方無限期後退時,誘導停止。
漸變路徑
傳導:傳導是一個端到端的過程。為了使傳導發生,應產生電位差或溫差。
誘導:誘導不需要梯度路徑。
