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.

V = I * R
V = 110
I = 3.5
R = 110/3.5 = 31.428.
V = 110
I = 3.5
R = 110/3.5 = 31.428.

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

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.

According to ohms law, I is directly proportional to V.
so. V=IR
R=v/I
R=110/3.5=31.42.
so. V=IR
R=v/I
R=110/3.5=31.42.

According to ohm's low R =V/I,
V= 110V.
I = 3.5A.
Put the value of voltage and current above formula given.
R = 110/3.5.
Correct answer is 31 ohm.
V= 110V.
I = 3.5A.
Put the value of voltage and current above formula given.
R = 110/3.5.
Correct answer is 31 ohm.

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.
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.

From the given question, it is related to ohm's law V=IR.
then,
from the question, V=110V and I=3.5A.
R=V/A=110/3.5=31.42=31.
then,
from the question, V=110V and I=3.5A.
R=V/A=110/3.5=31.42=31.
