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.
Then, I = V/R.
R = 110/3.5 = 31.4285.
Then, I = V/R.
R = 110/3.5 = 31.4285.

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
V=110V
I=3.5A
By Ohms law
V=IR
R=V/I
=110/3.5
=31.428
=31 Ohms
V=110V
I=3.5A
By Ohms law
V=IR
R=V/I
=110/3.5
=31.428
=31 Ohms

We known that, *according to ohm's law R = V/I =110/3.5 = 31.42 ohm.

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

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.

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.

Yes the 'D' is right answer i.e. R =31 ohms according to ohms law.

V = IR.
110 = 3.5*R.
R = 110/3.5.
R = 31.42 [CUT OFF].
R = 31.
110 = 3.5*R.
R = 110/3.5.
R = 31.42 [CUT OFF].
R = 31.
