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.

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.

As we know that from ohms law,
V = IR.
GIVEN,
V = 110V.
I = 3.5A.
SO R=V/I.
R=110/3.5 = 31.42 ohm.
i.e 31 ohm.
V = IR.
GIVEN,
V = 110V.
I = 3.5A.
SO R=V/I.
R=110/3.5 = 31.42 ohm.
i.e 31 ohm.

R = V/I.
R = 110/3.5 = 31.428.
Appro = 31.
R = 110/3.5 = 31.428.
Appro = 31.

Well 32 ohms would be right cause it's coming 31.428 so round off 32 ohm.

We know that from ohm's law.
V = IR.
Given, R=110/31.5 = 31.428
R = 31
V = IR.
Given, R=110/31.5 = 31.428
R = 31

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.

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.
