(a) A dc voltage source containing two or more cells that convert chemical energy to electrical energy
A (a) is a single slender rod or filament of drawn metal. This definition restricts the term to what would ordinarily be understood as (b) wire.
The word “slender” is used because the length of a wire is usually large when compared to its diameter. If a wire is covered with insulation, It is an (c) wire. Although the term “wire” properly refers to the metal, it also includes the insulation. A (d) is a wire suitable for carrying an electric current.
(a) Equipment that will operate on either an AC or DC power source
(a) Single unit used to convert chemical energy into a DC electrical voltage.
are constructed of one, single piece of metal. It is tougher than a stranded conductor, but rigid and less flexible than a stranded conductor. Solid conductors are more likely to break if subjected to frequent flexing than stranded conductors
Solid conductors
Stranded conductors
Solid insulators
Stranded insulators
it is either a stranded conductor (single‐conductor cable) or a combination of conductors insulated from one another (multiple‐conductor cable).
is a general one and usually applies only to the large sizes of conductor. it may be bare or insulated.
Solid conductors
Stranded conductors
Solid insulators
Stranded insulators
Cables
It is a conductor composed of a group of wire or any combination of group of wires. The wires in this conductor are usually twisted together and not insulated from each other.
Solid conductors
Stranded conductors
Cable conductor
Stranded insulators
it is a device used to break an electric current or transfer it to another conductor. commonly used to open or close a circuit. Closed is the ON position, while open is OFF position.
