State the formula co$-$relating the electric current flowing in a conductor and the voltage applied across it. Also, show this relationship by drawing a graph. What would be the resistance of a conductor, if the current flowing through it is $0.35$ ampere when the potential difference across it is $1.4$ volt ?
State the formula co$-$relating the electric current flowing in a conductor and the voltage applied across it. Also, show this relationship by drawing a graph. What would be the resistance of a conductor, if the current flowing through it is $0.35$ ampere when the potential difference across it is $1.4$ volt ?
It states that "Physical conditions remaining same the current flowing through a conductor is directly proportional to the potential applied across its two ends."
The graph is as shown below
Given $V=1.4 V , I =0.35 A$
Now, resistance is given by the expression
$R =\frac{ V }{ I }=\frac{1.4}{0.35}=4 \Omega$
