Which equation represents ohm's law?

Literally, ohm's law implies that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).

Mathematically, this can be represented as:

`I\ \alpha\ (V)/(R)`

Convert the expression to an equation

`I\ =\ (V)/(R)`

Multiply both sides by R to make V the subject

`I\ * R\ =\ (V)/(R) * R`

`I\ * R\ =V`

Reorder

`V = I\ * R`

`V = IR`

Option (a) is correct; Others are not
