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...

Hey, My Name is Md Kaif and I am from Bihar, India. ![]()
I am an Electrical Engineer. 😊
My blog is about electrical things, theories, syllabus, and all all things related to electrical engineering.
I have post many topics like construction of dc machine, lap winding, wave winding, armature winding, armature reaction, characteristics of dc machine.
In future, I will post so many topics like network theory, power system, signal and system, analog electronics, digital electronics etc.

Wave Winding in detail
Wave winding We know that, Y c is commutator pitch Here Y c ≠ 1 but Y c ≈ 2S/P Assume S=16 and P=4. Coil span = S/P =16/4 =4, Y c = 8 The first coil is (1-5') and terminated on commutator 1 and 9. The second coil (9-13') to be connected in series with the first and to be terminated on commutator segment (9 + 8 = 17). Since there are only 16 commutator segments so 17 is identical to 1. Hence, we terminate where we started and cannot connect any more coils in series. Our inability to complete the winding, will persist till 2S is a multiple of P. So, we modify the expression for Y c = 2(S ± 1)/P No. of poles, P = 4 No. of slots, S = 17 Winding pitch, Y c = 2(S+1)/P choosing +1 for progressive winding Y c = 2(17+1)/4 = 9 Coil span = S/P = 4 First segment (1-5') starts from 1 and ends at 20, where second coil starts and ends on commutator segment-2 Between any two consecutive commutator segments (P/2) coils will be present winding progresses like a wave.

CHARACTERISTICS of DC GENERATORS (Separately Excited)
1. No-Load Characteristics It is the curve between Induced emf and Field current, E a = f (I f ) with speed (n) = constant This is called as saturation curve, open-circuit characteristic, magnetization curve or no-load magnetization curve. 2. Load Characteristics It is the curve between terminal voltage and field current, V t = f (I f ) with both 'I a ' and 'n' constant This is called as load magnetization curve. 3. External Characteristics It is the curve between terminal voltage and load current, V t = f (I L ) with both 'I f ' and 'n' constant 4. Armature Characteristics It is the curve between field current and armature current, I f = f (I a ) with both 'V t ' and 'n' constant This is called as Regulation Curve. Separately Excited Generator 1. No-Load Characteristics The set-up for plotting No-Load Characteristics is shown in the above figure. By varying the field resistance we can vary the field curren...
CHARACTERISTICS OF DC COMPOUND GENERATOR
Cumulatively Compound Generator are more common as compared to Differentially Compound Generator as they have almost constant voltage from No-Load to Full Load. 1. No-Load Characteristics For long shunt, due to lesser number of turns in series field winding, series MMF does not impact the no-load characteristics. For short shunt, series field winding does not carry any current and this no-load characteristics is same as that of shunt generator. Hence, in both cases no-load characteristics are same as that of a Shunt Generator. 2. External Characteristics In cumulatively compounded generator, series flux adds shunt flux and depending upon number of series field turns, It is classified as Under-compounded: V t falls with load Flat-compounded: V t is practically constant Over-compounded: V t rises with load In differentially compounded generator, series flux opposes shunt flux and thus V t falls more rapidly with load. If we plot the character...
