What will happen to the current flowing through a conductor,if the potential difference is doubled?

Name and define the $SI$ unit of current. Calculate the number of electrons that flow through a conductor in $1$ second to constitute a current of $1$ ampere. (Charge on an electron $= 1.6 \times 10^{-19} \text{ C}$)

$1 \text{ kWh} = 3.6 \times 10^6 \text{ joules}$. Is this statement true or false?

Explain the term resistance. Give its $SI$ unit of measurement.

List any two factors on which the resistance of a conductor depends.

Three $V-I$ graphs are drawn individually for two resistors and their series combination. Out of $A, B, C$,which one represents the graph for the series combination of the other two? Give a reason for your answer.
