RICH DAD POOR DAD BOOK REVIEW

  RICH  DAD  POOR  DAD  BOOK REVIEW This is amazing book.   • Explodes the myth that you need to earn a high income to become rich • Challenges the belief that your house is an asset • Shows parents why they can't rely on the school system to teach their kids about money • Defines once and for all an asset and a liability • Teaches you what to teach your kids about money for their future financial success It's been nearly 25 years since Robert Kiyosaki’s  Rich Dad Poor Dad  first made waves in the Personal Finance arena. It has since become the #1 Personal Finance book of all time... translated into dozens of languages and sold around the world. Rich Dad Poor Dad  is Robert's story of growing up with two dads — his real father and the father of his best friend, his rich dad — and the ways in which both men shaped his thoughts about money and investing. The book explodes the myth that you need to earn a high income to be rich and explains the difference between working

LOOP-CURRENT METHOD and NODE-VOLTAGE METHOD

 Basic terms




Junction :- A Junction is a point, where three or more circuit elements are joint.
                          From the circuit it is obvious that B and D points are junctions point.

Branch :- The part of the network lies between two junction point is called branch.
                        BD, BAED, BCFD are branches in above circuit.

Loop :- The closed path of the network is called loop.
                  ABDEA, BCFDB, ACFEA are branches in above circuit.

Mesh :- The most elementary part of the loop is called mesh.
                   ABDEA, BCFDB are mesh in above circuit.


Loop-Current Method :- This method which is particularly well-suited to coupled circuits solutions employs a system of loop or mesh currents instead of branch currents. Here, the currents in different meshes are assigned contineous paths. So that they do not split at junction into branch currents.

Step-by-step procedure for solving loop currents method :-
  1. All the currents sources are converted into voltage sources.
  2. Clockwise loop currents are chosen, loops are usually selected so that no inner loops exists within a chosen loop.
  3. The loop equations are written in sequence for loops 1,2,3.....N

Node-Voltage Method :- The node voltage method is based on kirchoff's current law. but, loop current method is based on KVL.
In this method junction is regarded as node. one of these node is regarded as reference node. hence, the number of simultaneous equation to be solved becomes (n-1) where, 'n' is the number of nodes.
The procedure for solving network by using node voltage method.
  1. All the voltage sources are converted into current sources.
  2. A reference node 'R' is chosen, its selection is arbitrary, other node in the circuit are assigned letters A,B,C.......N are unknown voltages EA, EB .....EN  are chosen as voltage rises from node 'R' to the nodes A,B.....N etc.
  3. The node equation are written in sequence for nodes A,B.....N  etc.
