Yes the 'D' is right answer i.e. R =31 ohms according to ohms law.

According to ohms law state that resistance is directly proportional to voltage and inversely proportional to the current. so
R=V/I
R=110/3.5
R=31.42
option D correct
R=V/I
R=110/3.5
R=31.42
option D correct

According to ohms law.
V=IR.
Therefore.
R=V/I.
R=110/3.5.
=31.4 ohms.
V=IR.
Therefore.
R=V/I.
R=110/3.5.
=31.4 ohms.

V = IR.
R = V/I.
R = 110 / 3.5.
R = 31.42 ohm.
R = V/I.
R = 110 / 3.5.
R = 31.42 ohm.

V=IR.
V=110V
I=3.5A
R=?
R=V/I
R=110/3.5
R=31.4
R=31ohm.
V=110V
I=3.5A
R=?
R=V/I
R=110/3.5
R=31.4
R=31ohm.

Voltege=110v
Current=3.5A
According to the ohms law V = IR
110 = 3.5*R
R = 31 Ohm
Current=3.5A
According to the ohms law V = IR
110 = 3.5*R
R = 31 Ohm

Ohms law is are proportional to I inversely to V at content physical parameters like temperature and stress on conductor etc. It is right.

Yes according to ohms law
V = IR
R = V/I
= 110/3.5
= 31 ohm
V = IR
R = V/I
= 110/3.5
= 31 ohm

R=V/I
=110/3.5
=31.4~31ohm
=110/3.5
=31.4~31ohm

YES, R=V/I
=110/3.5
= 31OHM.
=110/3.5
= 31OHM.
