dudes...................if u dont get any iit and nit trichy ....
THEN DONT THINK TOO MUCH.............go for any degree in BITS.
U JUST CANT COMPARE BITS WIT ALL THOSE PRIVATE COLLEGES...................
TRY BITSAT..............ALONG WIT AIEEE AND JEE............
|
|
|
|
dude...............
if u wana a private college............come to BITS......................
|
|
|
|
i hope u wanaa physical interpretation.............
look............................
potential difference is the work done by a unit charge to move from one point to another.
consider a circuit wit a wire AB ,a battery C,and a resistor R.
THE POTENTIAL ALONG THE WIRE(excluding the resistance) is same.since no work has to done by a charge to mave in a conductor.because electric feild inside a conductor is zero or we can say tht the feild is perpendicular to the motion of the electrons.
now when it come to the resistance............the charge feels a resistance to its easy flow.........so some work has to be done by the charge to overcome this resistance.if we could get tht work (.........somehow........)and divide it with the total charge flowing u get the potential difference.............
from calculations we get tht the potential difference acrss the resistance is just the== i x R.
U CAN GET THE VALUE OF i from the ammeter put in the cicuit.
now ur second question..........
all cell have some thing inside them with which they work......
chemicals r common inside the batteries......these chemicals cant be expected to work wit 100% efficiency.the inefficiency in them effect the free flow of elctrons.
thus charges have to do some work to overcome the internal resitance wit in the cell.so the effective potential we get is the total potential(EMF) - potential lost due to resitance = effective potential of the cell....................
hope u got it................
if satisfied plz rate me................................

and let me tell u .........i used to show magic to 4th standard students using a capacitor...........
first i will charge the capacitor using a battery ,behind the stage.then i used to bring an LED and connect it to the capacitor.all the students were astonished to see the LED glowing witout a battery.(they dont know abt capacitors...........hahhaahaha).
but after glowing the LED came the real trouble.............since its not possiable to make it glow too long(charge stored is very less),the bulb start to unglow slowly..................
but i managed to end the show before it get OFF.........

u r right.....................a very gud question.
but it has some problems.....
1.......the discharge done by a capacitor is very quick.
2........to chaqrge the capacitor we need a battery.then y to use a capacitor?
3........and of course we r using it for things like.....flashes in a camera were quick discharge is needed.......
4.......moreover economically its not easy to produce a capacitor tht can store high amount of current.hope u know the dimensions of the
capacitor tht can store 1C charge.so i think its not possiable to use it
as a battery..................
if useful give me the rates.................................

just an answer to ur question................
wht u mean by electricity?
if charge moves uniformly over a point in a given time we say there is an electric current.this process results in electricity.
in a conductor when it is put in an electric feild,then the charge get distributed themselves in the conductor to cancel the electric feild.so in a conductor there is no electric feild.
so the charges r moving.we can say there is a process of electricity...
it may be foolish .........but i cooked this to answer ur question........
if satisfied rate me..................

luk this method.............
calculate the effetive resistance.=8 ohms
calculate the total current in the circuit.=10 A
now...
divide 10A in the ratio 6:12
so u get (20/3)A will flow through 6 ohms and (10/3)A will flow through 12 ohms.
similarly in the next branching also (20/3)A will flow through 6 ohms and (10/3)A will flow through 12 ohms.
so the net current through AB will be =(10/3)A in the direction from A to B.......
U CAN GET THIS BY THE CONCEPT OF CONSERVATION OF CHARGES......
plz rate me ..............if correct

yes.......u need proper 80% in board level to write BITSAT.......
remember 79.99999999999999999%<80%...............
next time it will be made to 85%....
my seniours r telling so....................

dude..........i am from kerala.which enginearing college r u asking?
is it CET(college of enginearing trivandrum)?
if so i would say tht its a better option than VIT.
but it is damn difficult to get there......u have to clear kerala entrance examination with a high rank(<100) to get electronics related subjects.
plz dont beleive those college rankings.......if u calculate the average IQ of those students in CET,it will be much much greater than the most brillant student of VIT..........
U CAN SAY THT CET RANKING IS LESS THAN VIT JUST BECAZ the college is not made decorative as VIT............
if u get both CET AND VIT .................go for cet............
and if u get BITS CET VIT................go for BITS.............
and if u get IIT BITS CET VIT................U KNOW WHTS THE ANSWER.......

karthik can u explain ur point.............
i feel answer could be found by......
ENERGY STORED AS KINETIC= -(energy lost by friction)
energy lost to friction can be foung by integrating the frictional force x dx over the 0 to x......
but then u get a expression wit bot x and x^2
plz analyze my method and find the mistake
|
|
|
|
|
inttead of trying VIT............go for a better option .............BITS
|
|
|
|
just divide the different ways possiable...
ie
12 c 3 / 15 c 3
it has nothing to do with bayes theorem
|
|
|
|
u r right............nit trichy is better than BITS GOA.
JUST BECAZ ...................................bits goa is a new institute.
let someone ask the same question after 7-10 years .........let see wht will be the reply.................

wht u mean by electrical intesity........
is it electrical feild intesity?
wht is x here?
