Given data
V = 110 volt.
I = 3.5 A.
We know that;
According to Ohm's law-
V = IR.
So, R = V/I
R = 110/3.5
R = 31.4 Ohm.
V = 110 volt.
I = 3.5 A.
We know that;
According to Ohm's law-
V = IR.
So, R = V/I
R = 110/3.5
R = 31.4 Ohm.

Ohm's Law firm v = IR.
Then R = V/I.
Given;
V = 110v.
I = 3.5A.
Therefore
R = 110/3.5 = 31.428.
So, the given answer is correct.
Then R = V/I.
Given;
V = 110v.
I = 3.5A.
Therefore
R = 110/3.5 = 31.428.
So, the given answer is correct.

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.

From the given question, it is related to ohm's law V=IR.
then,
from the question, V=110V and I=3.5A.
R=V/A=110/3.5=31.42=31.
then,
from the question, V=110V and I=3.5A.
R=V/A=110/3.5=31.42=31.

At constant temperature Current flowing through the conductor is directly proportional to the applied voltage.
Formula;
I=V/R
Formula;
I=V/R

We know that Resistance = Potential difference/strength of current.
R = V/I.
= 110/3.5.
= 31.428.
Rounded off,
R = 31 ohms.
R = V/I.
= 110/3.5.
= 31.428.
Rounded off,
R = 31 ohms.

Yes, According to problem voltage(v) is 110v and Current(I)=3.5A.
Then R=V/I=110/3.5=31.42 then approximately=31ohm.
Then R=V/I=110/3.5=31.42 then approximately=31ohm.

Ohms law V=IR.
Then R=V/I.
Given,
V=110v.
I=3.5A
Therfore R=110/3.5=31.428.
So the given answer is correct.
Then R=V/I.
