The expressions that correctly represent variations of Ohm's Law are:

  1. P = IV (Power in terms of current and voltage, where P is power).
  2. V = IR (Voltage in terms of current and resistance).
  3. R = V/I (Resistance in terms of voltage and current).
  4. I = V/R (Current in terms of voltage and resistance).

The incorrect expression from your list is:

  • R = IV (This is not a correct representation of Ohm's law).

So, the correct options are:

  • P = IV
  • V = IR
  • R = V/I
  • I = V/R
