Introduction To Electric Circuits -

: A device that consumes electrical energy and converts it into another form, such as a light bulb (light), a motor (motion), or a heater (heat).

: Provides the electrical "pressure" (voltage) to move charges. Examples include batteries (DC) and wall outlets (AC). Introduction to Electric Circuits

: A reference point and safety feature that provides a return path for current. The Core Laws of Electricity : A device that consumes electrical energy and

: A device used to open or close the circuit path. An "open" circuit has a break that stops current flow; a "closed" circuit is a complete loop. : A reference point and safety feature that

: Conductive materials, usually copper wires, that provide the physical path for electricity to travel.

speaking it's actually the charge value divided by the time. now we the unit for charge is kulum. and the unit for time is second. YouTube·PhysicsHigh 1B: Introduction to Electronic Circuits
