Electric resistance material

Japanese: 抵抗材料 - ていこうざいりょう(英語表記)electric resistance material
Electric resistance material
A material used for resistors. When a certain voltage E is applied to a material, a certain current I flows, and the resistance of the current to flow can be expressed as E / I. This value is called electrical resistance. An element that exhibits a certain level of electrical resistance is called a resistor, and it plays an unsung hero role supporting electronics, the star of modern times. Various alloys or carbon are used as resistor materials. In metals, it is the conduction electrons that move freely from atom to atom that carry the current.

Japanese:
抵抗に用いられる材料。物質にある電圧Eをかけると,ある一定の電流Iが流れるが,このときの電流の流れにくさはE/Iで表すことができる。この値を電気抵抗という。一定の電気抵抗を示す素子は〈抵抗〉と呼ばれ,現代の花形であるエレクトロニクスを支える縁の下の力持ち役を果たしている。抵抗の材料には種々の合金あるいは炭素が用いられている。金属中で電流を担っているのは原子から原子へと自由に動きまわっている伝導電子である。
