Voltage Drop: When to use Ohm's Law Method vs. Formula Method

[nbabcock03]

Rounding out my 4th and final year of Mike Holt's education course, I am confused about when the course material wants me to use the Ohm's Law Method or the Formula Method for single-phase voltage drop. Can either method be used interchangeably when solving for single-phase?

Both interchangeably based on data in problem but if Mikeeholt prefer one method specific problems, follow

Both methods should result in the same (or very nearly so) solution.
