Question

Six resistors each of $10\Omega$ are connected as shown. Find the equivalent resistance in ohms between points $X$ and $Y$.

Answer 1

Equivalent resistance of wheatstone bridge between points X & Y $\Rightarrow 10\Omega$

which is in parallel with another 10$\Omega$, so $\Rightarrow R_{eq.}=\frac{10\times 10}{10+10}=5\Omega$
