    The physical significance of curl of a vector

    Re: Electromagnetics just like if the end of a pipe is closed at one end,the water circulates in the pipe this is known as curl

    Electromagnetic waves in metal

    well propagation of em waves thru metal is cretainly not desirable if it is to be seen a a propagation medium,skin effect plays havoc .

    Math where is it taking us?Are we justified in studying it?

    well this is not a crazy idea my dear friend,this is an intricate question that drives one into tizzy.but lets look at it this way.suppose u see a bird,how do u make out that its a bird only.perhaps u hav some sort of visual perception that makes u figure out that what u see is a bird.this...

    Which electronic university course is most practical?

    electronic course start off with basic courses such as microelectronics circuits n digital stuff.later if u wanna pursue a job in the field just study vlsi n languages such as vhdl

    How to solve this Physics Problem

    this is an easy problem.just resolve the tension into corresponding components n then using f=mg get the result

    where does energy go?

    well whatever the case, energy is always conserved.the dissipation of energy may vary from case 2 case,but overall energy is conserved.lets suppose u hit a batt with ur bat.so of the energy is lost in form of heating the bat.the rest is transferred to the ball n it gains momentum,now when the...

    The physical significance of curl of a vector

    Electromagnetics curl is a wonderful concept.its what accounts for em wave propagation.imagine a waterpipe closed at one end.now when the liquid flowing in the wire encounters this closed end,it circulates in the pipe this is curl effect.for further details u can always look into feynman's...

    Electromagnetic waves in metal

    well theres no current involved in em wave propagation.energy flows here in form of electric n magnetic fields which travel orthogonally.

    Why do we use complex numbers

    why we use complex number complex no is special for the reason that it has 2 components.one real n other imaginary again confusing,whats this real n imaginary stuff??? well in physics real is the one with reference phase n the imaginary is the 90 degree phase shifted version of real part.i hav...

    Effect of gravitational force

    well friend,u no this is just a delusion.gravity is same. yet quantitatively the two r different.vertical motion makes u spend Mgh amount of energy while as horizontal motion makes u spend enerry depending on various factors as friction,the manner in which force is applied.but the point to...

    Help me understand the hall field effect in semiconductors

    SEMICODUCTOR PHYSICS well dear friend,its simple we no that whenever u place a current carrying conductor in a magnetic field ,it experiences a force n the direction is determined by flemings rule.now if u apply electic field to a conducor,current constitutes.applying a transverse magnetic...
