$A$ $V-i$ graph for a conductor is given. The resistance is proportional to which of the following?

The charge $q$ (in coulomb) passing through a $10 \, \Omega$ resistor as a function of time $t$ (in second) is given by $q = 3t^2 - 2t + 6$. The potential difference across the ends of the resistor at time $t = 5 \, s$ is: (in $V$)

The $V-i$ graph for a conductor makes an angle $\theta$ with the $V$-axis. Here $V$ denotes the voltage and $i$ denotes the current. The resistance of the conductor is given by:

For a wire,$\frac{R}{l} = \frac{1}{2} \, \Omega/cm$ and the length of the wire is $l = 5 \, cm$. If a potential difference of $1 \, V$ is applied across it,the current through the wire will be: $(R = \text{Resistance})$ (in $A$)

Ohm's law is true for which of the following?

The variation of current $(i)$ and voltage $(V)$ in a conductor is shown in the diagram below. The resistance of the conductor is ........... $\Omega$.
