For assignment 2, I choose elctricity as my concept of this project and
how many times I use to switch on the plug at three different area;
kitchen, living room and living room upstairs. I recorded the usage in 1
week/ 7 days
Electricity
.
In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:
- electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields.
- electric current: a movement or flow of electrically charged particles, typically measured in amperes.
- electric field (see electrostatics): an especially simple type of electromagnetic field produced by an electric charge even when it is not moving (i.e., there is no electric current). The electric field produces a force on other charges in its vicinity. Moving charges additionally produce a magnetic field.
- electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts.
- electromagnets: electrical currents generate magnetic fields, and changing magnetic fields generate electrical currents
Cable
Electric cables discussed here are mainly meant for installation in buildings and industrial sites. For power transmission at distances greater than a few kilometres see high-voltage cable, power cables, and HVDC.
Plug
AC power plugs and sockets are devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building. Electrical plugs and sockets differ in voltage and current rating, shape, size and type of connectors.This plug, commonly called a 13 A plug or 13 amp plug, has three rectangular pins forming an isosceles triangle. Line and neutral are nominally 4 by 6.35 mm (0.157 by 0.250 in) and 17.7 mm (0.697 in) long, on centres spaced 22.2 mm (0.874 in) apart. 9 mm (0.354 in) of insulation at the trailing ends of the pins prevents accidental contact with a bare connector while the plug is partially inserted. The earth pin is nominally 4 by 8 mm (0.157 by 0.315 in) and 22.7 mm (0.894 in) long.
