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

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.
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.

According to ohm's law voltage is directly proportional to current in a specified conductor having some resistance.
i.e V = RI.
I = V/R.
I = 110/3.5.
I = 31.4 A.
i.e V = RI.
I = V/R.
I = 110/3.5.
I = 31.4 A.

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.

Given:
V = 110 volt.
I = 3.5 amp.
R = ?
We know that:
According to ohm's law:
I = V/R.
V = IR.
R = V/I.
=110/3.5.
=31.428.
Hence answer is 31 ohm.
V = 110 volt.
I = 3.5 amp.
R = ?
We know that:
According to ohm's law:
I = V/R.
V = IR.
R = V/I.
=110/3.5.
=31.428.
Hence answer is 31 ohm.

According to Ohm's law V=IR.
But we need 'R'.
So bring the I to this side then it will be divided by V,
As given below,
R=V(110)/I(3.5)
R=31.4 ohms.
But we need 'R'.
So bring the I to this side then it will be divided by V,
As given below,
R=V(110)/I(3.5)
R=31.4 ohms.

According to ohm's low R =V/I,
V= 110V.
I = 3.5A.
Put the value of voltage and current above formula given.
R = 110/3.5.
Correct answer is 31 ohm.
V= 110V.
I = 3.5A.
Put the value of voltage and current above formula given.
R = 110/3.5.
Correct answer is 31 ohm.

Yes according to Law I = VR.
V = 110 V, I = 3.5 A & R=?
There fore we want Resistance so that R = V/I.
R = 110/3.5.
R = 31.42 or R = 31 Ohm.
V = 110 V, I = 3.5 A & R=?
There fore we want Resistance so that R = V/I.
R = 110/3.5.
R = 31.42 or 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.

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
