According to ohm's law V = IR

Resistance = voltage/current
=110/3.5
=31.4

Reshma said: (Dec 18, 2010)  
Ya its absolutely right.......

R.Ashok said: (Jan 22, 2011)  
According ohm's law it states that the resistance is directly propostional to the voltage & inversly propostional to the current at constant temprature.
i.e R=V/I
R= 110/3.5
R=31.4285ohm so here we are taking approximative value 31.

Amir said: (Feb 27, 2011)  
I(A)=voltage/resistance
or
I=E/R
or
R=E/I
= 110/3.5
=31.42
=31

Chittaranjaan said: (Mar 6, 2011)  
Ya right, but if there would be another option stating 32 then..

Swamy.M said: (Mar 7, 2011)  
Yes, I accept it is correct because according to ohm's law state that"resistance is directly propostional to the vg,and invesly propostional to current. Hence we can conclude that I=V/R

I=3.5,v=110,R=?
R=V/I,R=110/3.5=31.42 apprsmtly=31 we can put. that solve.

Ravidas Nayak said: (Jan 21, 2016)  
In accordance with ohm's law, current through DC circuit is given by I = V/R.

Here we want to know the value of hating material, that is R.

Since I and V is given so the value of R is given by R = V/I.

That is 110/3.5 which is 31.4.

Saikiran said: (Mar 13, 2016)

Oyelowo Oluwatobiloba said: (Sep 12, 2017)  
From
V = IR
(where V is the Voltage (volts), I current (Ampere), and R resistance(ohms)

V=110v
I=3.5A
R=?

Making R subject from V=IR by dividing through by I
We have R=V/I
R=110/3.5
R= 31.4ohms

Approximately 31ohms.

Er.Mukesh Kumar said: (Oct 2, 2017)  
According yo law, 31 is right.

Put the value of voltage and current above formula given.
R = 110/3.5.

Correct answer is 31 ohm.

Deepak Prakash said: (Nov 30, 2017)  
According to ohms law, I is directly proportional to V.
so. V=IR
R=v/I
R=110/3.5=31.42.

Shubham Pandey said: (Jan 23, 2018)  
Acc. To ohm's law.
V=IR.
Or R= V/I.
Then,
R=110/3.5.
=>1100/35.
=31.42.

Bibek said: (Apr 7, 2018)  
The correct answer is 31.4 Ω.

T Ashok said: (Jun 9, 2018)  
Resistance =voltage /current.

So, R =110/3.5,
So, R =110/35/10,
So, R =110/35 *10,
R=31.4 Ω.

Pabitr Akumar Behera said: (Dec 12, 2018)  
V = I * R
V = 110
I = 3.5
R = 110/3.5 = 31.428.

Aman said: (Mar 13, 2019)  
According to this,
if you want to simplify the voltage then it will be, V=R * A(V=>31 * 3.5 = 108.5).

Voltage means to push, so push must have to multiply by A(amount of electron) and R(anti-push).

And if you want to simplify the R(anti-push).
Then,
R(anti-push) = V(push)/A(amount of electron),
R = V/A.
