In accordance with ohm's law, current through DC circuit is given by I = V/R.
Here we want to know the value of hating material, that is R.
Since I and V is given so the value of R is given by R = V/I.
That is 110/3.5 which is 31.4.

V = IR.
R = V/I.
Given V = 110 V, I= 3.5 A.
R = 110/3.5 = 1100/35 = 22O/7 = 31.42~31.
Make calculations easy.
R = V/I.

By using for OHMS law.
Given:
R = V/I.
So, R = 110/3.5 = 31.42.
Answer: 31 OHM.
Given:
R = V/I.
So, R = 110/3.5 = 31.42.
Answer: 31 OHM.

Ohm law V = IR.
V = 110V, I=3.5A, R=?,
R = V/I,
R = 110/3.5,
R = 31.42857142857143,
R = 31 OHM.
V = 110V, I=3.5A, R=?,
R = V/I,
R = 110/3.5,
R = 31.42857142857143,
R = 31 OHM.

V = IR.
V = 110.
I = 3.5.
R = V/I = 110/3.5 = 31.
V = 110.
I = 3.5.
R = V/I = 110/3.5 = 31.

V = lR.
R = v\l.
V = 110 v.
I = 3.5 A.
R =110\3.5 = 31.4 ohm.
R = v\l.
V = 110 v.
I = 3.5 A.
R =110\3.5 = 31.4 ohm.

According to Ohm's law:
V = IR,
R = V/I,
R = 110/3.5,
R = 31.42.
V = IR,
R = V/I,
R = 110/3.5,
R = 31.42.

According to ohm's law V = IR.
Then, I = V/R.
R = 110/3.5 = 31.4285.
Then, I = V/R.
R = 110/3.5 = 31.4285.

Ohms law states that at constant temperature the current flowing through the conductor is directly proportional to potential different between the two end of the conductor.
That is V = IR.
That is V = IR.
