If the resistance of a wire is $50\,\Omega$,the graph between $\log\ V$ and $\log\ I$ is........

Which of the following graphs represents an ohmic resistance?

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

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

The variation of current $(i)$ passing through a conductor as the voltage $(V)$ applied across its ends is varied is shown in the adjoining diagram. If the resistance $(R)$ is determined at the points $A, B, C$ and $D$,we will find that

$A$ potential difference of $10 \,V$ is applied across a conductor of $1000 \,\Omega$. The number of electrons flowing through the conductor in $300 \,s$ is ..........
