![]() The cathode is the electrode where electricity is given out or flows out of. The anode is the electrode where electricity moves into. However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow. In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. It’s because the protons are attracted to the cathode, so it’s mainly positive, and therefore is positively charged. Since electrons carry a negative charge, then the anode is negatively charged. In a galvanic cell, electrons will move in to the anode. Hence, known as a cathode while the anions migrate to a positively charged anode, and so-known as the anode. They are so-called because the cations, which are positively charged, migrate to the negative cathode. What are the charges at the cathode and anode?Īns: A Cathode is a negative electrode, whereas the anode is a positive electrode. For example, in a recharging battery the cathode is negative. However, the polarity of the cathode with respect to anode can either be negative or positive, and it largely depends on the operation of the device. ![]() During charge the positive is an anode, the negative is a cathode.Ī cathode is a negatively charged electrode. For example, in an electron tube electrons from the cathode travel across the tube toward the anode, and in an electroplating cell negative ions are deposited at the anode.ĭuring discharge the positive is a cathode, the negative is an anode. ![]() In a battery or other source of direct current the anode is the negative terminal, but in a passive load it is the positive terminal.
