Please help! How would I simplify this?

Please help me simplify this. Thanks!


1/(1/R + 1/R )


There is a 1 subscript for the 1st R and a subscript of 2 on the second R.

Substitue in some numbers for R1 and R2, I suggest you use primes, and evaluate the expression.


1/(1/R + 1/R )


See if this gives the same answer.


1/[(R(1) + R(2)]/[R(1)*R(2)]


= 1 * [R(1)*R(2)]/[(R(1) + R(2)]


... R(1) * R(2)
= -------------
... R(1) + R(2)

Hello, Muppers3262!

Please help me simplify this.

. . . . . . .1
. . . -------------
. . . . .1 . . .1
. . . . --- + ---
. . . . R₁ . .R₂
.

Multiply top and bottom by R₁R₂:

. . . . . . . . . . . . . R₁R₂
. . . and get: . ------------
. . . . . . . . . . . . R₂ + R₁
