$A$ $60\,W$ bulb operates on a $220\,V$ supply. The current flowing through the bulb is:

$A$ $220\, V$,$1000\, W$ bulb is connected across a $110\, V$ mains supply. The power consumed will be ............ $W$.

The resistor of resistance $R$ is connected to a $25\, V$ supply and the heat produced in it is $25\, J/s$. The value of $R$ is .......... $\Omega$.

In India,electricity is supplied for domestic use at $220\,V$. It is supplied at $110\,V$ in the $USA$. If the resistance of a $60\,W$ bulb for use in India is $R$,then the resistance of a $60\,W$ bulb for use in the $USA$ will be:

If the current through a bulb changes by $1\%$,what is the percentage change in the power consumed?

The power wasted in the connecting wires of voltage $V$ and finite resistance $R_C$ from the power station to the device of power $P$ is . . . . . . .
