Final answer:
The expressions that correctly represent variations of Ohm's law are P = IR and V = IR.
Step-by-step explanation:
The expressions that correctly represent variations of Ohm's law are:
- P = IR - This equation relates power (P), current (I), and resistance (R).
- V = IR - This equation relates voltage (V), current (I), and resistance (R).
The other expressions listed do not accurately represent variations of Ohm's law.
