2. Ohm's law - Wikipedia

   en.wikipedia.org/wiki/Ohm's_law

   Equations for time-invariant AC circuits take the same form as Ohm's law. However, the variables are generalized to complex numbers and the current and voltage waveforms are complex exponentials. [29] In this approach, a voltage or current waveform takes the form Ae st, where t is time, s is a complex parameter, and A is a complex scalar

4. ANSI device numbers - Wikipedia

   en.wikipedia.org/wiki/ANSI_device_numbers

   In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations.

5. Circuit diagram - Wikipedia

   en.wikipedia.org/wiki/Circuit_diagram

   A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

6. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   An AC circuit experiences 100% voltage reversal, while underdamped DC circuits experience less than 100%. Reversal creates excess electric fields in the dielectric, causes excess heating of both the dielectric and the conductors, and can dramatically shorten the life expectancy of the capacitor.

7. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy ...

8. Electronic component - Wikipedia

   en.wikipedia.org/wiki/Electronic_component

   Electronic components have a number of electrical terminals or leads. These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like ...

9. AC power plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/AC_power_plugs_and_sockets

   e. AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit.
