This also applies when the customer gives the seller a valid resale certificate or other exemption document.
In a discharging battery (Galvanic cell), the anode is the negative terminal, and cathode is positive. In a recharging battery (Electrolytic cell), the opposite happens, anode is positive and cathode is negative. Here, the mnemonic PRANC (rhymes with prank) can be used, P- Positive.
Components of a corrosion cell â¢ Anode â Metal loss or corrosion occurs at the anode â¢ Cathode â Little or no corrosion occurs at the cathode â¢ Return Circuit/Metallic Path â Provides a path for electrons to flow, between the anode and cathode â¢ Electrolyte â Ionized solution capable of conducting electricity.
