R=V/I
GIVEN:
VOLTAGE(V)=110V
CURRENT(I)=3.5A
RESISTANCE(R)=V/I=110/3.5\
ANS=31.42~31

According to ohm's law
V=IR =>R=V/I
=>R=110/3.5
R=31.4
V=IR =>R=V/I
=>R=110/3.5
R=31.4

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.

according to ohms law
V=IR OR R=V/R
WE CAN PUT I=3.5 & V=110 THEN
R=110/3.5=31.4
V=IR OR R=V/R
WE CAN PUT I=3.5 & V=110 THEN
R=110/3.5=31.4

At constant temperature Current flowing through the conductor is directly proportional to the applied voltage.
Formula;
I=V/R
Formula;
I=V/R

Ohm's law cab be stated in workd as the current in a resistive circuit is directly proportional to its applied voltage and inversely proportional to its resistance.
Formulas are;
I=V/R or V=IR or R=V/I
Formulas are;
I=V/R or V=IR or R=V/I

Given
V=110V
I=3.5A
By Ohms law
V=IR
R=V/I
=110/3.5
=31.428
=31 Ohms
V=110V
I=3.5A
By Ohms law
V=IR
R=V/I
=110/3.5
=31.428
=31 Ohms

Its exactly correct. We have to remember this formula.
V=IR.
V=IR.

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