An electrical bulb rated $220\,V, 100\,W$ is connected in series with another bulb rated $220\,V, 60\,W$. If the voltage across the combination is $220\,V$,the power consumed by the $100\,W$ bulb will be about $........... W$.

Find the equivalent resistance between point $A$ and $B$ in the following circuit. (The resistance of each resistor is $R$)

Two bulbs,one of $200 \ V, 60 \ W$ and the other of $200 \ V, 100 \ W$,are connected in series to a $200 \ V$ supply. The power consumed will be ................ $W$.

First,a set of $n$ equal resistors of $R$ each are connected in series to a battery of $emf$ $E$ and internal resistance $R$. $A$ current $I$ is observed to flow. Then,the $n$ resistors are connected in parallel to the same battery. It is observed that the current increases $10$ times. What is $n$?

$A$ wire has a resistance of $24\,\Omega$ and is bent into the shape shown in the figure. The effective resistance between $A$ and $B$ is .............. $\Omega$.

In a series connection of resistors,is the current equal or the voltage? And in a parallel connection of resistors,is the current equal or the voltage?
