What is the anode?
The anode is an electrode in the electrical system by which the electrical current enters the system. Depending on the type of system, this electrode can be positive or negatively charged, in most cases it has a positive charge. The anodes are part of batteries and electrically charged tanks that are used for polarization or storage of layers of various metals. There are also a number of devices that use special types of electrodes called sacrificial anodes, to protect other metal components.
batteries that are galvanic cells use anodes to transmit energy from the chemical process on the inside of the cell to the device. Although most anodes are positively charged, in this case the anode is a negative side of the battery. In these devices, the metal in this electrode slowly dissolves into a liquid as part of the chemical reaction that takes place in the battery. Once the electrode has completely dissolved, the batteries no longer have the batteries that are able to recharge, switch the function of the anode and the cathodes when charging, allowing RedEposition of metal on the anode. In these cases, the anodes are on the positive side of the electrical system. Energy travels to these types of systems through the anode and leaves through the diode. While the energy enters the system in this way, the electrons leave the system through the anode.
sacrificial anodes are used in devices such as water heaters. They get their name from how it "sacrifices" it to maintain other materials in equipment such as a metal water heater tank. Electricity used to power this type of device causes metal components to crumble over time, so that they are placed sacrificial anodes in order to prevent other metal components from deteriorating. As long as the anode is made of metal, which is more active than metal in the rest of the device, the place of other metals deteriorates. In some cases, the presence of less active metal can accelerate the deterioration of anode metal, which means that it is possible to frequentlyi replace.
