Its exactly correct. We have to remember this formula.
I=V/R or V=IR or R=V/I.
I=V/R or V=IR or R=V/I.

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.

Acc. To ohm's law.
V=IR.
Or R= V/I.
Then,
R=110/3.5.
=>1100/35.
=31.42.
V=IR.
Or R= V/I.
Then,
R=110/3.5.
=>1100/35.
=31.42.

I(A)=voltage/resistance
or
I=E/R
or
R=E/I
= 110/3.5
=31.42
=31
or
I=E/R
or
R=E/I
= 110/3.5
=31.42
=31

According to ohm's law V = IR
Resistance = voltage/current
=110/3.5
=31.4
Resistance = voltage/current
=110/3.5
=31.4

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

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

According to ohms law.
V=IR.
Therefore.
R=V/I.
R=110/3.5.
=31.4 ohms.
V=IR.
Therefore.
R=V/I.
R=110/3.5.
=31.4 ohms.

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.
