4) Preventing breast cancer. Regular consumption of most alcoholic drinks increases the risk of breast cancer. However, red wine intake has the opposite effect, researchers from Cedars-Sinai Medical Center in Los Angeles found.
Voltages are produced by converting one form of energy into electrical energy. Mechanical energy can be converted into electrical energy (voltage and current) by moving a magnet or magnetic coil in proximity with a stationary coil, connected to an electrical circuit. A voltage can also be produced with a chemical reaction. Batteries and fuel cells convert energy in specially designed cells, where a chemical reaction causes a voltage to exist across two electrodes implanted at two different parts of the cell. A voltage can be produced by the interaction of light on a photocell. The photons of light interacting with atoms in the photocell, cause an electron to be ejected. The special design of the photocell causes this to occur in such a manner as to produce voltage across the cell. A voltage can be produced by subjecting a thermocouple to differential temperature. A thermocouple is a relatively simple device composed of two dissimilar metals, joined together at what is referred to as a thermal junction.
One way to store it is in the form of chemical energy in a battery. When connected in a circuit, energy stored in the battery is released to produce electricity. If you look at a battery, it will have two ends: a positive terminal and a negative terminal. If you connect the two terminals with wire, a circuit is formed.
