In electricity and electronics, the relationship among the combined resistance of two resistors wired in a parallel circuit is described by the formula 1/r=1/r1+1/r2, where r1 and r2 are the resistances of the two resistors and r is the combined resistance.

(a) Find the combined resistance of two 12 ohm resistors.
I got 1/6 as my answer is this correct?

(b) If the combined resistance is 2000 ohms, and one of the resistors is 3000 Ohms, find the resistance of the other resistor.

And for this one my answer was 6000 Ohms.
 
I'm not really doubting just double-checking to make sure I made no errors because these problems are worth a lot of points in my lesson.
 
How to solve two resistors in parallel

This post is very old, In fact, 10 years but I am replying here so as to help other members who visit the link:
1. Solving two resistors in parallel will give 6 as an answer and not 1/6.

2. The second one is right, it is 6000.
