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.
1 Definition: The anode of a device is the terminal where current flows in from outside. The cathode of a device is the terminal where current flows out. This is illustrated in figure 1.  A useful mnemonic is ACID : Anode Current Into Device.
Electrons flow from the cathode to the anode. Not the other way. There are tubes with three, four, and more elements, but they have these two basic elements. Chemistry The cathode is the electrode of a polarized electrical device, such as a galvanic cell, out of which positive electric current flows.
