Question

Hi! I was wondering if you could help with this question please :)​

Answer 1

`R=(QJ)/(I^2t)`

Explanation:

So we have the equation:

`Q=(I^2Rt)/(J)`

And we want to solve for R.

First, let's multiply both sides by J to remove the fraction on the right. So:

`(J)Q=(J)(I^2Rt)/(J)`

Simplify the right:

`JQ=I^2Rt`

We can rewrite our equation as:

`JQ=R(I^2t)`

So, to isolate the R variable, divide both sides by I²t:

`(JQ)/(I^2t)=(R(I^2t))/(I^2t)`

The right side cancels, so:

`R=(QJ)/(I^2t)`

And we are done!
