Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Electrical phenomena are commonplace and unusual events that can be observed and that illuminate the principles of the physics of electricity and are explained by them.
Electrical phenomena are a somewhat arbitrary division of
electromagnetic phenomena.
Some examples are

Biefeld–Brown effect — Thought by the person who coined the name, Thomas Townsend Brown, to be an anti-gravity effect, it is generally attributed to electrohydrodynamics (EHD) or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics.
Contact electrification — The phenomenon of electrification by contact. When two objects were touched together, sometimes the objects became spontaneously charged (οne negative charge, one positive charge).
Direct Current  — (old: Galvanic Current)  or "continuous current"; The continuous flow of electricity through a conductor such as a wire from high to low potential.
Electroluminescence — The phenomenon wherein a material emits light in response to an electric current passed through it, or to a strong electric field.
Electrical conduction — The movement of electrically charged particles through transmission medium.
Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body.
Ferroelectric effect — The phenomenon whereby certain ionic crystals may exhibit a spontaneous dipole moment.
Inductance  —  The phenomenon whereby the property of a circuit by which energy is stored in the form of an electromagnetic field.
Lightning —  powerful natural electrostatic discharge produced during a thunderstorm. Lightning's abrupt electric discharge is accompanied by the emission of light.
Photoconductivity —  The phenomenon in which a material becomes more conductive due to the absorption of electro-magnetic radiation such as visible light, ultraviolet light, or gamma radiation.
Photoelectric effect —  Emission of electrons from a surface (usually metallic) upon exposure to, and absorption of, electromagnetic radiation (such as visible light and ultraviolet radiation).
Piezoelectric effect — Ability of certain crystals to generate a voltage in response to applied mechanical stress.
Plasma — Plasma occur when gas is heated to very high temperatures and it disassociates into positive and negative charges.
Pyroelectric effect — The potential created in certain materials when they are heated.
Static electricity  —  Class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltages of sufficient magnitude to produce visible attraction (e.g., static cling), repulsion, and sparks.
Sparks  — Electrical breakdown of a medium that produces an ongoing plasma discharge, similar to the instant spark, resulting from a current flowing through normally nonconductive media such as air.
Telluric currents — Extremely low frequency electric current that occurs naturally over large underground areas at or near the surface of the Earth.
Thermionic emission — the emission of electrons from a heated electrode, usually the cathode, the principle underlying most vacuum tubes.
Thermoelectric effect — the Seebeck effect, the Peltier effect, and the Thomson effect
Thunderstorm — also  electrical storm, form of weather characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere known as thunder.
Triboelectric effect — Type of contact electrification in which objects become electrically charged after coming into contact and are then separated.
Whistlers — Very low frequency radio wave generated by lightning
