ACT 科学 - 電磁気学と力学

the electronic potential and force whose measurement unit is volts

電圧

an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

抵抗器

the complete circle through which an electric current flows, typically consists of the source of electric energy

電気回路

a solid substance that conducts electricity or heat better than insulators, but not as well as most metals

半導体

a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures

超伝導

to apply an electric charge to a conductor

電気を通す

a conductor through which electricity travels to or from an object, such as batteries

電極

a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons

アノード

a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit

陰極

a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces
