Current and voltage source

[Eddy boy]

In circuit analysis, what is the difference between voltage and current source ??current exits only when there is some potential difference then why we say only current source ?solve it!

[Eddy boy]

If any body know a good book of circuit analysis/electric circuit then plz tell me.

[rohit.kush]

network analysis and snthesis by "chakrabarti"

[anujarora1]

go for S.K SHADEV

[gauds]

"Fundamentals of electric circuits" by Alexander and Sadiku

[Eddy boy]

oh! its too difficult to select which one book is perfect for me.

Gauds please tell me about the contents of fundamentals of electric circuits

[gauds]

It is divided into three parts,Dc circuits,AC circuits and Advanced circuit analysis.

DC circuits-basic laws,theorems,op-amps,L,C,first-order and second-order circuits,node and mesh analysis.

AC circuits-Phasors,source transformation,three phase circuits,power analysis frequency response,mag coupled circuits,

Advanced circuits analysis- Laplace transform and applications,Fourier series,Fourier Transform,two port networks
(With PSPICE Examples and a small intro about MATLAB

thanks ...

well, a "source" means it has to maintain the parameter which it is source of, thus a voltage source has to maintain the voltage across its terminals regardless of the current through it ( for example if resistance is doubled in the circuit, current will be halved but voltage must remain same... V=IR )

a current source has to maintain the current through it regardless of the voltage across it ( for example if resistance is doubled, votage across its terminals will also be doubled but current through it will remain the same.... I= V/R )

got it brother?

Is a battery is a voltage source? if yes then how ? it does not maintain voltage across its terminals when load resistance is altered...please give example of voltage source if any?
