Ohm's Law, ΔV = I • R, can be rewritten several ways. Which of the following is an incorrect way to rewrite Ohm's Law?

Question

I = ΔV / R

R = ΔV / I

I / ΔV = R

1 / R= I / ΔV

Answer 1

Looks like it's time to review your Algebra I
At the very least, plug a few numbers and play around to see what fails.

12 = 3•4
Now start rearranging the numbers.

hint. (b) and (c) cannot both be true in general, unless ΔV/I = I/ΔV
