Electricity

Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electric current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.

In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:

Electric guitar

An electric guitar is a guitar that uses a pickup to convert the vibration of its strings—which are typically made of metal, and which occurs when a guitarist strums, plucks or fingerpicks the strings—into electrical impulses. The vibrations of the strings are sensed by a pickup (music technology), of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock.

Invented in 1931, the amplified electric guitar was adopted by jazz guitarists, who sought to be able to be heard in large big band ensembles. Early proponents of the electric guitar on record included Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker, and Charlie Christian. During the 1950s and 1960s, the electric guitar became the most important instrument in pop music. It has evolved into an instrument that is capable of a multitude of sounds and styles. It served as a major component in the development of electric blues, rock and roll, rock music, and many other genres of music.

Electric car

An electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration. They are also around three times as efficient as cars with an Internal combustion engine.

The first electric cars were produced in the 1880s. Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engines and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicles. The energy crises of the 1970s and 1980s brought a short-lived interest in electric cars; although, those cars did not reach the mass marketing stage, as is the case in the 21st century. Since 2008, a renaissance in electric vehicle manufacturing has occurred due to advances in batteries and energy management, concerns about increasing oil prices, and the need to reduce greenhouse gas emissions. Several national and local governments have established tax credits, subsidies, and other incentives to promote the introduction and adoption in the mass market of new electric vehicles depending on battery size and their all-electric range.

Nissan Leaf

The Nissan Leaf (also formatted "LEAF" as a backronym for leading environmentally-friendly affordable family car) is a compact five-door hatchback electric car manufactured by Nissan and introduced in Japan and the United States in December 2010, followed by various European countries and Canada in 2011. The U.S. Environmental Protection Agency (EPA) official range for the 2016 model year Leaf with the 30 kWh battery is 172 km (107 miles) on a full battery charge, while the trim with the smaller 24 kWh battery is 135 km (84 miles), the same as the 2014/15 model year.

As of December 2015, the Nissan Leaf is the world's all-time best selling highway-capable all-electric car. Leaf global sales passed the 200,000 unit milestone in December 2015, five years after its introduction. As of December 2015, the top markets for Leaf sales are the United States with over 89,000 units, followed by Japan with over 57,000 units, and Europe with over 49,000 Leafs. The European market is led by Norway with over 15,000 new units, and the U.K. with over 12,000 units registered.

You Can

"You Can" is a 1981 single by Madleen Kane and produced by Giorgio Moroder. The song was written by Yolanda Yvette Adams, Donald Ray Atkins and Marcus Ecby. Along with the track, "Fire in My Heart", "You Can" was Kane's most successful single on the dance charts, spending three weeks at number one. The single was her only Hot 100 chart entry, peaking at #77.
