Insulators like wood and rubber have a very low electrical resistance.

$1 \; kWh = \ldots \ldots \ldots \; \text{watt-seconds}$

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 $\text{ V}$)?

In an electric circuit,state the relationship between the direction of conventional current and the direction of flow of electrons.

You are given three resistors of $10\, \Omega, 10\, \Omega, 20\, \Omega$,a battery of emf $2.5\, V$,a key,an ammeter,and a voltmeter. Draw a circuit diagram showing the correct connections of the given components such that the voltmeter gives a reading of $2.0\, V$.

What is the maximum resistance which can be made using five resistors each of $1/5 \ \Omega$ (in $\Omega$)?
