Học thuậtThân thiện
Definition
- Adjective:
- Pertaining to or associated with a cathode: Describes something that relates to, is located at, or involves the cathode, which is the negatively charged electrode in an electrical device or system, such as a battery or an electrolytic cell.
Usage
- The term "cathodic" is primarily used in scientific and technical contexts, especially in physics, chemistry, and engineering. It is used to describe processes, properties, or components related to the cathode.
- It is often used attributively (before a noun) to modify other terms.
Examples
- Adjective:
- Cathodic protection is a technique used to control the corrosion of a metal surface.
- The researcher studied the cathodic reaction occurring in the fuel cell.
- Cathodic deposition is a common method in electroplating.
Advanced Usage
- "Cathodic polarization": A decrease in the potential of a cathode, often discussed in electrochemistry.
- Cathodic polarization can affect the rate of metal deposition.
- "Cathodic current": Electrical current that flows toward or through a cathode.
- The experiment measured the cathodic current in the circuit.
Variants and Related Words
- Cathode (n): The electrode where reduction (gain of electrons) occurs; the negative terminal in a device that consumes electricity (e.g., a battery during discharge).
- Anodic (adj): Pertaining to or associated with an anode (the positively charged electrode). This is the direct antonym in electrochemical contexts.
Synonyms
- Negative-electrode-related (descriptive synonym, less common)
- Pertaining to the cathode (definitional synonym)
Antonyms
- Anodic: Pertaining to or associated with an anode.
Adjective
- of or at or pertaining to a cathode
- cathodic deposition of metals
