Final answer:
To solve the formula for resistance (R), multiply both sides of the equation P = V²/R by R to isolate R. The formula for resistance is R = V²/P.
Step-by-step explanation:
To solve the formula for resistance (R), we can rearrange the equation P = V²/R. Multiply both sides of the equation by R to move it down to the denominator, resulting in R = V²/P. So, the formula for resistance is R = V²/P.
