Question
Calculate net resistance between $\mathrm{A}$ and $\mathrm{B}$(A)(B) $(4 r / 3)$(C) $(3 \mathrm{r} / 4)$(D) $2 \mathrm{r}$
Step 1
The equivalent resistance of resistors in parallel is given by the formula: \[R_{eq} = \frac{1}{\frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}}\] where $R_1$, $R_2$, and $R_3$ are the resistances of the individual resistors. Show more…
