the positive terminal of a voltaic cell or battery. The cathode acts as an electron acceptor. An anode is an electrode where the electricity moves into. If electrons always flow into the cathode (by way of definition of cathode), this statement implies that the cathode can be at a positive voltage relative to the anode. cathode kath-ohd noun the electrode or terminal by which current leaves an electrolytic cell, voltaic cell, battery, etc. A cathode is an electrode from where the electricity flows out or is given out. How would you define this term clearly and unambiguously? Does the common use of the term “cathode” really reverse when the current carrier is positive, as suggested in the article?Įdit: What actually confuses me is the phrase “Cathode polarity is not always negative”. positive ions gain electrons from the negatively charged cathode negative ions lose electrons at the positively charged anode. The positive electrode in a voltaic cell, such as a battery, toward which. The cathode has a negative charge because it is connected to the negatively charged end of an external power supply. Browse the use examples copper cathode in the great English. If the definition is referring to the current carriers, then the definition might be rephrased as “cathode is an electrode through which the charged current carriers flow out” (or “in”?). cathodes synonyms, cathodes pronunciation, cathodes translation, English dictionary definition of cathodes. Check out the pronunciation, synonyms and grammar. Hence, this definition seems to be a bit lacking. However, the direction of current flow is purely an arbitrary convention, and is in fact the opposite direction to which electrons flow in a metal conductor. But there are only five cathode active materials that perform as a battery. According to Wikipedia’s definition, a cathode is “an electrode through which electric current flows out of a polarized electrical device”. Definition of cathode the negatively charged electron source in an electronic valve C19: from Greek kathodos in an electron tube, the negatively charged. Numerous active materials can be created with lithium, oxygen and other materials.
