An anode and a cathode are the two types of terminals in an electronic device. The cathode is the terminal where current leaves an electronic device. The anode is the terminal where current flows into an electronic device. Electrical current is the amount of charge that passes a fixed point in one unit of time.Know More
In a standard battery, such as a D-size flashlight battery, the anode is the positive terminal and the cathode is the negative terminal. The anode of a battery is involved in an oxidation reaction. Electrons that reside in the anode are transferred into the electrolyte as a result of this reaction. The cathode of a battery is involved in a reduction reaction. This results in the cathode gaining electrons from the electrolyte. Excess electrons in the cathode are forced out through the circuit and back into the anode. Electrons are negatively charged and are repelled by the negatively charged cathode. The force of this repulsion is called voltage.
In other electronic devices the polarity is reversed. The anode is the negative terminal and the cathode is the positive terminal. The flow of current remains the same. Current always flows out of the cathode and into the anode.Learn more about Chemistry
Leaded gasoline is gas that has been mixed with a lead-containing chemical, tetraethyllead, whereas unleaded gasoline does not have the added lead. Gas with lead in it was phased out in the United States starting in 1973 and was completely banned for on-road vehicles in 1996.Full Answer >
The difference between iron and steel is that iron is an element, and steel is an alloy of iron, small amounts of carbon and another material, usually another element like chromium. Iron is alloyed with other elements to make it stronger and more useful and to keep it from rusting.Full Answer >
There are several distinct differences between silicone and latex rubbers, the primary difference being that latex is a natural product and silicone is man-made. Consumers may choose between silicone and latex versions of several plastic products, including pacifiers, caulking and rubber bands.Full Answer >
Enantiomers are isomers that are mirror images of each other and diastereoisomers are those that are neither mirror images nor the same molecule. In both cases the molecules have the same atoms connected to each other in the same way. The differences between these isomers are the spatial arrangements of the atoms based on the 3D-bond geometry.Full Answer >
