option A)
volt ÷ ampere
Step-by-step explanation:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points the constant of proportionality, where resistance is constant.
Ohm's LawI = V / R
rearranging it in terms of R will give
R = V / I
V- voltage is measured in volts
I - current is measured in ampere
So,
ohm = volts / ampere
or
ohms = volt ÷ ampere
