Both the anode and cathode are immersed in an electrolyte solution, and electricity flows from the negative to positive parts of your battery via the conductor. Cathodes are named after cations (positively charged ions), while anodes are named after anions (negatively charged ions).Ī cathode is essentially there to obtain electrons from the anode. An anode, on the other hand, is the electrode in a polarised electrical device throughout which current flows in from an external circuit. In a polarised electrical device, the cathode is the metallic electrode by which current flows. Just keep in mind that any motion of charged particles is current. This can be perplexing because the direction of current is defined by the movement of a positive charge. Because the cathode can generate electrons, which are typically the electrical species that do the actual movement, it is possible to say that cathodes generate charge or that current flows from the cathode to the anode. It is capable of accepting positive charges. The cathode is either an electron donor or a source of electrons. The cathode tends to attract cations or positively charged particles. The negatively charged electrode is the cathode. Current flows in the opposite direction of negative charge carriers like electrons in metals. When positive charge carriers, such as ions or protons, carry the charge, current flows in the same direction. Why is it defined in this manner? Who knows, but this is the rule. So, if electrons move in a cell, current flows in the opposite direction. However, keep in mind that current direction is determined by where a positive charge would move, not where a negative charge would move. ![]() Current, in its broadest sense, makes reference to any movement of electrical charge. The flow of current defines the anode and cathode.
