How do I solve for L:d=Lh/R1+R2?

I want to view final answer

To solve for L in the equation d = Lh / (R1 + R2), you can follow these steps:

1. Multiply both sides of the equation by (R1 + R2) to eliminate the denominator:

d * (R1 + R2) = Lh

2. Divide both sides of the equation by h to isolate L:

(d * (R1 + R2)) / h = L

So the solution for L is given by:

L = (d * (R1 + R2)) / h

By plugging in the values of d, R1, R2, and h into this equation, you can calculate the value of L.
