Resistance = Voltage / Current
= 1.4/0.8
= 1.75 ohms.

It can be simplified by using the formula V=I x R (Ohm`s law),providing there is no inductive and capacitive loss.
So.R(Resistance) = V(Voltage across the wire)/I(Current passing through it).Therefore R =1.4/0.8=1.75 Ohm.

V=IR therefore R=V/I
Given V=1.4
Given I=0.8
thus, R= 1.4/ 0.8 = 14/8 ==1.75

resistence is the obstuction to the flow of current in a substance when supllieda voltage.. the three are related by ohm's law.. it is given by volage = current*resistance... hence resistance = voltage/current= 1.4/0.8=1.75ohms.. the unit of resistance is itself ohm.

Resistance = Voltage divided by Current.
answer = 1.75 Ohms (if DC voltage)
