Two common types of circuits are series and parallel. An electric circuit consists of a collection of wires connected with electric components in such an arrangement that allows the flow of current within them. A series circuit has no branches but instead has several components arranged one after th

According to The United States Potato Board, seven types of potatoes are commonly enjoyed by consumers: russet, long white, round white, fingerlings, red, yellow and blue or purple. The potato industry refers to them as table-stock varieties.

While the George Mateljan Foundation for the World's Healthiest Foods considers potatoes an excellent source of vitamin B6, potassium, copper, vitamin C, manganese, phosphorus, niacin, dietary fiber and pantothenic acid, it cautions that most people eat potatoes deep fried with extra fat, which is u

A 20-amp circuit is an electrical circuit designed to carry an electrical load of up to 20 amperes at a time. Electrical appliances draw current, measured in amperes. Measuring the current draw of an appliance is a matter of knowing its wattage and the voltage.

Potatoes were first eaten and cultivated in the Andean highlands of South America, between Bolivia and Peru. Spread to Europe and North America by Spanish explorers, these tubers are ranked second among the world's most staple crops.

A short circuit is caused when two or more uninsulated wires come into contact with each other, which interferes with the electrical path of a circuit. The interference destabilizes normal functioning of electricity flow. The resistance generates a lot of heat in the wires and can lead to a fire.

Potatoes do eventually go bad. Their exact shelf life depends on the type of potato, but most go bad after two to five weeks at room temperature or two to four months in a refrigerator.

Circuit boards, also known as printed circuit boards, are thin metal coated plates containing electronic components found in electronic and communication devices. The components transfer information and signals to each other and to external devices using etches made by acid on the metallic surface.

Potato diseases include infestations of the root, leaves and tubers caused by bacteria, fungi and other viruses. Common potato diseases include potato wart, soft rot and potato blight, according to the American Phytopathological Society. A complete list of potato diseases can be found on the U.S. De

An electric circuit works by providing a closed loop to allow current to flow through a system. Electrons must be able to flow throughout the circuit, completing a path from one pole of the power source to the other. Along the way, this flow of electrons can be used to power lights or other electric
