Resistance may not be measured in decimal. So answer in 31 ohm is correct.

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

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.

I = 3.5A.
V = 110V.

By ohm's law,
V = IR.

110 = 3.5R.
R = 31 ohm.

What is the proper definition of ohm's law?

Kshitiz said:   1 decade ago
According to ohm's law V = IR.

Resistance = voltage/current.

= 110/3.5.

= 31.4 ohm.

I = V/R.
R = V/I.
R = ?

V = 110V.
I = 3.5A.

R = 110/3.5.
R = 31.428.

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

Use of the ohm's law R = V/I. So, V=110V , I=3.5A then,

R = V/I = 110/3.5,

1100/35 = 31.428.

ANS - 31 ohm.

Shobhana said:   1 decade ago
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.
