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.

According to Ohm's law.
I = V/R.
So, R = V/I.
R = 110/3.5 = 31.4286Ω.
I = V/R.
So, R = V/I.
R = 110/3.5 = 31.4286Ω.

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.

As per ohms law R = V/I.
V = 110V.
I = 3.5.
R = 110/3.5 = 31.42.
ANS R = 31OHMS IS THE RIGHT ANSWER.
V = 110V.
I = 3.5.
R = 110/3.5 = 31.42.
ANS R = 31OHMS IS THE RIGHT ANSWER.

As per ohms law,
Voltage V = 110.
Current I = 3.5.
Resistance R = X.
Formula,
R = V/I.
R = 110/3.5 = 31.42 ohms.
Resistance of heating element is 31.42 ohms.

R = V÷I.
R = 110÷3.5.
= 3.1 Ohms.
R = 110÷3.5.
= 3.1 Ohms.
