Line Resistance in Transmission Line

Line Resistance in Transmission Line  :- 👉Every electric conductor oppose the flow of current in it ,this is known as resistance. 👉The power loss (I^2R) in the transmission line occurs due to this resistance. 👉The ohmic resistance R of a conductor of length ' l ' and uniform cross sectional area 'a',                                  R= ρl/a  Where, R=Total resistance in Transmission Line, ρ=Resistivity or specific resistance of conductor material , l=Length of the conductor, a= Area of cross section, 👉The Resistivity or specific resistance of the conductor is depends not only on the conductor material but also it's temperature. 👉For example ,if ρ₁ and ρ₂ are the values of resistivity at different temperatures t₁ and t₂ ,then ρ₂=ρ₁{1+α(t₂-t₁)} Where, a = Temparature coefficient of resistance of the material. 👉The value of the temparature coefficient of resistance is also not constant but depends upon the initial temparature  [0°C]. 👉Th

Difference between Node and Junction

Difference between Node and Junction :-   1)NODE:-    A point at which two or more elements are joints together is called node.    2)JUNCTION:-      While a point   where three or more        branches  meet   together  is  called   a junction.                   In the below figure we can say that points  a,b,c,d,e  and  f  are  nodes     and point  c &  f  are  called   junction.  While point c & f itself a node. Nodes -> a,b,c,d,e,f Junctions ->c,f  By observing above node and junction we can say that,  every junction becomes a node but every node not becomes a junction. ● SHARE IT
