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 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.
i.e R=V/I
R= 110/3.5
R=31.4285ohm so here we are taking approximative value 31.

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