Electrical Resistance is Denoted by 'R' and is the amount of opposition caused by a circuit in the flow of current.
Under normal/standard conditions The potential difference across the ends of a electrical circuit is directly proportional to the current flowing through it ,
Potential Difference is denoted by V and Current is denoted by I
when we remove the proportionality sign then a the equation becomes
V = IR
or I = V / R , Here R is the resistance offered by the circuit.
hence current is inversely proportional to the Resistance. It opposes the flow of current.
If we will plot a graph between V and I it will we a linear graph , as R is constant in this case.
