State the formula correlating 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 $0.35 \ A$ when the potential difference across it is $1.4 \ V$?

(N/A) The relationship is defined by Ohm's Law, which states that: "Provided the physical conditions (like temperature) remain constant, the electric current flowing through a conductor is directly proportional to the potential difference applied across its two ends."
The formula is $V = I \times R$, where $V$ is potential difference, $I$ is current, and $R$ is resistance.
The graph of potential difference $(V)$ versus current $(I)$ is a straight line passing through the origin.
Given:
Potential difference $(V)$ = $1.4 \ V$
Current $(I)$ = $0.35 \ A$
Using Ohm's Law, the resistance $(R)$ is calculated as:
$R = \frac{V}{I}$
$R = \frac{1.4}{0.35}$
$R = 4 \ \Omega$
Thus, the resistance of the conductor is $4 \ \Omega$.
