Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:
Simplify the right:
We can rewrite our equation as:
So, to isolate the R variable, divide both sides by I²t:
The right side cancels, so:
And we are done!
