V = IR.
So 110 = 3.5 R.
R = V/I.
So R = 110/3.5.
So R = 31.42.
So Answer D.
So 110 = 3.5 R.
R = V/I.
So R = 110/3.5.
So R = 31.42.
So Answer D.

Given:
V=110V.
I=3.5A.
R=?
Solution:
R= V/I.
R= 110/3.5.
R= 31 ohms.
V=110V.
I=3.5A.
R=?
Solution:
R= V/I.
R= 110/3.5.
R= 31 ohms.

Yes its correct.
By using the ohm's law we get,
R = V/I.
Therefore;- R = 110/3.5.
= 31.42 ohm.
Answer: 31 ohm.
By using the ohm's law we get,
R = V/I.
Therefore;- R = 110/3.5.
= 31.42 ohm.
Answer: 31 ohm.

Use of the ohm's law R = V/I. So, V=110V , I=3.5A then,
R = V/I = 110/3.5,
1100/35 = 31.428.
ANS - 31 ohm.
R = V/I = 110/3.5,
1100/35 = 31.428.
ANS - 31 ohm.

I = V/R.
R = V/I.
R = ?
V = 110V.
I = 3.5A.
R = 110/3.5.
R = 31.428.
R = V/I.
R = ?
V = 110V.
I = 3.5A.
R = 110/3.5.
R = 31.428.

According to ohm's law V = IR.
Resistance = voltage/current.
= 110/3.5.
= 31.4 ohm.
Resistance = voltage/current.
= 110/3.5.
= 31.4 ohm.

I = 3.5A.
V = 110V.
By ohm's law,
V = IR.
110 = 3.5R.
R = 31 ohm.
V = 110V.
By ohm's law,
V = IR.
110 = 3.5R.
R = 31 ohm.

We know that the current is directly proportional to voltage and inversely proportional to resistance.
So,
I = V/R.
R = V/I.
= 110/3.5.
= 31.42 ohm.
So,
I = V/R.
R = V/I.
= 110/3.5.
= 31.42 ohm.
