Question

a pice of resistance R is cut into five equal parts out of which four of them are connected to form a square ABCD . fifth one is connected diagonally across BD . If a battery is connected across AC , what would equivalent resistance of circuit?

Answer 1

Each part have resistance R/5

And

It satisfies wistan bridge condition

... So diagonal part is of no use

And the resulting resistance will be

((R/5+R/5)^-1 + (R/5+ R/5)^-1)

=R/5

Ans-R/5

Answer 2

Answer:

R/5

Explanation:

THIS IS A WHEAT STONE BRIDGE SO BY W.B.G CONCEPT THE ANS IS FOUND TO BE R/5
