What is the solution for 1/r1 +1/r2=1/R plus each of the steps? Please help.

1/R = (r1 +r2)/(r1 r2)

R = (r1 r2)/(r1+r2)
Now please stop posting this same question.

Did you know?

Did you know that the solution to the equation 1/r1 + 1/r2 = 1/R can be found using an equation known as the reciprocal formula? This formula states that the sum of the reciprocals of two resistors, r1 and r2, is equal to the reciprocal of the total resistance, R. To solve this equation, you can follow these steps: 1. Simplify the equation by finding the common denominator for r1 and r2, which is r1*r2. 2. Multiply both sides of the equation by the common denominator to eliminate the fractions. 3. Distribute the common denominator to each term on the left side of the equation. 4. Rearrange the equation to isolate the total resistance term, R, on one side. 5. Finally, take the reciprocal of both sides of the equation to solve for R. If you're still unsure, don't hesitate to seek further assistance.
