If a customer separately arranges and pays for delivery of a taxable item by a third party, the seller of the item will only collect sales tax on its charge (see Delivery-only services, below).f the product or service being sold is not taxable, any charge to the customer for shipping or delivery is also not taxable. 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.
The anode is now defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. Each electrode may become either the anode or the cathode depending on the direction of current through the cell.A bipolar electrode is an electrode that functions as the anode of one cell and the cathode of another cell.hen the cell is being charged, the anode becomes the positive (+) and the cathode the negative (â) electrode. This is also the case in an electrolytic cell. When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.
