$$\frac{1}{41}=\frac{1}{R_1}+\frac{1}{R_2}$$The given equation relates the resistances, $R_1$ and $R_2$, in ohms, of two resistors arranged in parallel in a circuit with a total resistance of $41$ ohms, where $R_1$ and $R_2$ are positive. Which equation correctly expresses $R_1$ in terms of $R_2$?

A

$R_1=41+R_2$

B

$R_1=41-R_2$

C

$R_1=\frac{41R_2}{R_2+41}$

D

$R_1=\frac{41R_2}{R_2-41}$
