229By wheatstone bridge principle the resistance between BE and CF will be nullified...so 3 R's in series =3R and two such series connection in parallel...so R=3 :.I=V/R
=3/3=1
21the figure to this question represent(wheatstone) as shown below :
so I=V/R equivalent
=3/3
=1 ampere(Ans) (=d)
Akash Anand You can simply say that point B&E as well as C&F are equipotential so we can simply ignore the resistances between them.Upvote·0· Reply ·2013-07-01 06:32:55
Aditya Agarwal How can we say like that, that the current will divide equally and hence the potential will be the same.? - Akash Anand Due to symmetry..we can say it.
535then whats the difference in this and that?
why cant we say over here that i1 = I - i1, due to symmetry(same resistance immediately after the point of diversion?
