Question

Which expressions correctly represent variations of Ohm’s law? Check all that apply.

P = IR
V = IR
R = IV
R = V over I
I = V over R
V =

Answer 1

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
