An anode is the positively charged electrode, while a cathode is the negatively charged one. They are used in many applications, like powering everyday items or industrial machines. Applications of Anodes and CathodesĪnodes and cathodes are essential components of electrical systems. Additionally, they cast off ions from salts during discharge processes, making electrical production more efficient. Examples include zinc, tin-oxide, or lead-oxide anodes.Ĭathodes can be carbon or graphite, and they drive up positive charge build up. There are different types: anodes can be metal, oxide, or polymer. They control the direction of electron current flow in a circuit. Types of Anode and CathodeĪnodes and cathodes are key components in batteries and electroplating. Anodes give up electrons, cathodes absorb them. This causes electrons to flow from them to balance the charge. On the other hand, anions with a negative charge accumulate at anodes. This causes electrons to accumulate there, making the cathode side positive. In galvanic cells, cations move towards the cathode. When electricity passes through an electrolyte solution, it splits into cations and anions. Care must be taken to ensure electricity flows only one way. The direction of the electron flow depends on the type of current powering them. An anode functions as a source for electrons, while a cathode acts as a sink or receiver. This concept can be applied to all types of electrical systems. Anode is positively charged and cathode is negatively charged. Working Principle of Anode and CathodeĪnode and cathode are two electrodes in an electrical circuit. Current flows from low potential cations through wires, exiting from high potential anions. Cathodes have high electric potentials, emitting electrons out. The polarities of voltage are labeled plus (+) or minus (-).Īnodes let electrons in easily, and resist them leaving. Voltage applied across a circuit causes electrons to move in one direction only. Electrons enter at the cathode, then flow out of the anode. Anode is positive and cathode is negative. Definition of Anode and CathodeĪnode and cathode are terms used in electric circuits. In special cases, electrodes need to be inert so they don’t react with solution ions or other species. Cathodes can be metallic ( zinc) or non-metallic ( carbon). For example, batteries powered by their own ‘alien charge’ with just one electrode.Īnodes are usually made from metals like copper or aluminum, as they conduct electricity well. Although, some devices can be built using one type. Current flow rate, or amperage, depends on voltage and resistance across a circuit.Īn anode attracts positively charged particles and repels negative. An anode is where electrical current enters, and a cathode is where it exits. Anode and cathode are two electrode types used in electric circuits, and in processes such as electrolysis.
