Ohms law V=IR.
Then R=V/I.
Given,
V=110v.
I=3.5A
Therfore R=110/3.5=31.428.
So the given answer is correct

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.
R = V/I = 110/3.5,
1100/35 = 31.428.
ANS - 31 ohm.

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.

V = IR.
R = V/I.
Given V = 110 V, I= 3.5 A.
R = 110/3.5 = 1100/35 = 22O/7 = 31.42~31.
Make calculations easy.

According to Ohm's law,
Volatage is directly proportional to Current.
i.e. V=IR
R=V/I=110/3.5=31.428 ohms
Volatage is directly proportional to Current.
i.e. V=IR
R=V/I=110/3.5=31.428 ohms

Given that,
V = 110.
I = 3.5.
R = ?
According to ohms law V = IR:
R = V/I.
= 110/3.5 = 31.42 = 31.
V = 110.
I = 3.5.
R = ?
According to ohms law V = IR:
R = V/I.
= 110/3.5 = 31.42 = 31.

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.

As per ohms law R = V/I.
V = 110V.
I = 3.5.
R = 110/3.5 = 31.42.
ANS R = 31OHMS IS THE RIGHT ANSWER.
V = 110V.
I = 3.5.
R = 110/3.5 = 31.42.
ANS R = 31OHMS IS THE RIGHT ANSWER.

Yes, Itis absolutly correct. Always remember formula
V=IR V....voltage
I....ampere
R...ohms
V=IR V....voltage
I....ampere
R...ohms

Ohm law V = IR.
V = 110V, I=3.5A, R=?,
R = V/I,
R = 110/3.5,
R = 31.42857142857143,
R = 31 OHM.
V = 110V, I=3.5A, R=?,
