In a parallel circuit, the total resistance is defined as

$\displaystyle {R}{T}=\frac{{{R}{1}\cdot{R}{2}}}{{{R}{1}+{R}{2}}}$ where R1 and R2 are readings of two resistors.

Find the reading of resistor R2 where resistance of R1 is 0.8 ohms and the total resistance is 0.49 ohms.

Round your answer to the hundredths. No need to enter "ohms".
