apartment wiring - 2

1.the dash box mostly at a common place at the basement contains the starting point of the cat3 cable that moves through the apartment

electrical - fuse,trips

1.magnetic -- these type of trips will break based on the fact that when more current passes through
a metal it will have higher magnetic properties . This is made use in breaking
2.Thermal -- when more current is passed through a metal high heat causes it to expand , this property is also made use in creating trip

electrical - extension box

1.plug points are considered to be ideal, with voltage at them as per specification.
2.if extension boxes are used then, the voltage at ext points will have a drop proportional to
extension wire impedence, hence the appliances connected to it will have a different life span
than specified in its manual over long use.
3.since the points are connected in serial, the point farthest from the extension box will have
more drop compared to near one

ofdm-2

1.television broadcasts also use ofdm to multiplex channels,but rather than air they do it on a
metallic medium

2.lan hmmm it seems is not FDM and its TDM or its neither
