Based on the equation given in the lab manual, what is the equation to find the equivalent resistance of two resistors in parallel? note: i do not want inverse resistance, i'm asking for r = group of answer choices req = r1 + r2 latex: r_{eq}=\frac{\: 1}{r_1}+\frac{1}{r_2} r e q = 1 r 1 + 1 r 2 r e q = 1 r 1 + 1 r 2 latex: \frac{1}{r_{eq}}=\frac{\: 1}{r_1}-\frac{1}{r_2} 1 r e q = 1 r 1 − 1 r 2 1 r e q = 1 r 1 − 1 r 2 latex: r_{eq}\: =\: \frac{r_1\cdot r_2}{r_1+r_2}
