Title: What are Power Cords? Which Cord Powers Your Computer?

What are Power Cords? Which Cord Powers Your
Computer? You just cannot take away the
electrical oxygen we require for survival!
All our major day to day activities either are
contingent on machines or electricity or
both. We need machines and machines need
electricity. Electricity is the flow of
electrons through a conductor. Now, to
align that flow of electrons, we need a metal
conductor sheathed inside a poly vinyl chloride
insulator (PVC). This equipment typically known
as a power cord. Power cord, power connector,
mains cable or line cord - call it with any of
those names but the purpose it serves
would not change. These power cords let
you connect your electrical appliance
through itself with one of its ends plugged in
the wall socket or a wall extension board and its
other end is plugged in the receptacle installed
on the appliance, to build a system
of temporary connection.
Appliances which are purely power backed,
need these power cords to get connected
with the main electrical supply line for
powering and energizing itself. Few appliances
are battery backed and they majorly need
the connection only to recharge the
batteries. These cords are capable of carrying
alternating current as well as direct
current. One end of the power cords has the plug
and the other end has a connector. The connector
is inserted in the receptacle and the plug is
plugged in the wall socket. Both these
ends can be of male or female origin. NEMA
Power Cords Back in 1926, National
Electrical Manufacturing Association was
established in North America which
developed the NEMA 1 connector. The
connector itself dates back to roughly the
same time period. Today NEMA connectors are
generally used all over the North American
Continent and in countries which have
specified the NEMA standards.
The basic NEMA 1 power cord has 2 flat
pins which are almost 5 inches apart from
each other. If it also consists of round pin
right below the two flat pins, it is NEMA type 5.
The third pin is generally used for grounding
purposes and this kind of NEMA plug is often
called grounded plug. Computer Power
Cord Most of the computer desktops and
some instrument amplifiers, printers, monitor
and other portable devices use the c13
power cord which has a standard specified under
IEC 60320. A power cord with a country
specific standard power plug attached on one
end and a c13 power cord coupler to the other is
generally called an IEC cord or computer power
cord as it is majorly used in computer
applications. Standards and Specifications
The computer power cord, Electrotechnical
Commission standard determines the
c13 is described by International
with the 60320 standard. The electrical,
mechanical, thermal
requirements and safety operations of the
specified power cable
cord. The selection of the coupler connector also
depends upon the shape, dimensions and size of
the appliance to be connected with the power
cord. The c13 power cord is rated at 15A/250V and
10A/250V With the temperature rating up to
65 Celsius. This maximum temperature rating is
the pin temperature. The c13 power cord
contains Earth Contact and it also allows
rewirable connector.
