Potato batteries use the acids in the potato to start a reaction with two electrodes made of different metals that cause electrons to flow from one to the other through the potato, producing power. The potato acts as a salt bridge, connecting the anode, or negative electrode, to the cathode, or posi
A battery charging circuit in a car is the assembly that connects the alternator to the battery and sends electricity to the battery. The motion of the wheels is transferred to the alternator, which acts as a simple generator. Some energy, however, is always lost to friction and heat.
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
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.
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.
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.
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
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.
An electrical short circuit, also called a circuit interruption, often occurs when the wire coating is stripped or when a nail passes through the wire. This generates a spark, which can set fire to nearby combustible material or damage an appliance or other fixture connected to the wires.
A switch works by interrupting current flow around an electrical circuit. A basic switch is a binary device: it is either open (off) or closed (on). The simplest type of switch is one that comprises two metal strips that are brought into contact by a spring or some other form of actuating mechanism.
