$A$ heating element is designed to dissipate $2400 \, W$ when connected to $240 \, V$. The power it dissipates when it is connected to $120 \, V$ is (Assume that resistance of the filament is constant). (in $ \, W$)

If a power of $100\, W$ is being supplied across a potential difference of $200\, V$,the current flowing is ............ $A$.

Heat is produced at a rate given by $H$ in a resistor when it is connected across a supply of voltage $V$. If now the resistance of the resistor is doubled and the supply voltage is made $V / 3$, then the rate of production of heat in the resistor will be

In an electrical circuit,a battery is connected to pass $20\, C$ of charge through it in a certain given time. The potential difference between two plates of the battery is maintained at $15\, V$. The work done by the battery is ........... $J$.

$A$ bulb has a specification of $1\, kW$ and $250\, V$. The resistance of the bulb is .................. $\Omega$.

$A$ ($100\, W$,$200\, V$) bulb is connected to a $160\, V$ power supply. The power consumption would be ............. $W$.
