Vedclass · Answer

(A) Let the resistance of each individual resistor be $R$.$1$. Between points $P$ and $R$: There is a single resistor of value $R$ in the branch $PR$. Thus,$R_{PR} = R$.$2$. Between points $P$ and $Q$: There are two resistors in parallel in the branch $PQ$. Thus,$R_{PQ} = \frac{R}{2} = 0.5R$.$3$. Between points $R$ and $Q$: There are three resistors in parallel in the branch $RQ$. Thus,$R_{RQ} = \frac{R}{3} \approx 0.33R$.Comparing the values: $R > 0.5R > 0.33R$.Therefore,the maximum equivalent resistance is between points $P$ and $R$.

In the given circuit,if all resistors have the same value $R$,then the maximum equivalent resistance will be between which points?
