The quantity of charge flowing past a point multiplied by time is current.

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

The table given below provides the resistivity of three samples in $\Omega \cdot m$:

Sample	Resistivity $(\Omega \cdot m)$
$A$	$1.6 \times 10^{-8}$
$B$	$7.5 \times 10^{17}$
$C$	$44 \times 10^{-6}$

$(a)$ Which of them is a good conductor? Which is an insulator? Why?
$(b)$ $A$ wire of resistance $4 \ \Omega$ is folded on itself to double its thickness. Calculate the new resistance of the wire.

What is the current flowing through a $60 \ W$ bulb when it is connected to a $240 \ V$ line?

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

If $2 \times 10^{-3} \text{ J}$ of work is done in moving a particle carrying a charge of $10 \times 10^{-6} \text{ C}$ from infinity to a point $P$, what will be the potential at the point $P$ (in $\text{ V}$)?
