2. Electricity - Wikipedia

   en.wikipedia.org/wiki/Electricity

   The incandescent light bulb, an early application of electricity, operates by Joule heating: the passage of current through resistance generating heat. Electricity is a very convenient way to transfer energy, and it has been adapted to a huge, and growing, number of uses. [ 75 ]

3. Kirchhoff's circuit laws - Wikipedia

   en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

   The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:

4. Ohm's law - Wikipedia

   en.wikipedia.org/wiki/Ohm's_law

   Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, [1] one arrives at the three mathematical equations used to describe this relationship: [2]

   A 2006 report by a joint taskforce between the American Physical Society and the American Association of Physics Teachers found that 76 of the 80 physics departments surveyed require a first-year graduate course in John Jackson's Classical Electrodynamics. [4]

7. Sources of electrical energy - Wikipedia

   en.wikipedia.org/wiki/Sources_of_electrical_energy

   Friction is the least-used of the six methods of producing energy. If a cloth rubs against an object, the object will display an effect called friction electricity. The object becomes charged due to the rubbing process, and now possesses an static electrical charge, hence it is also called static electricity. There are two main types of ...
