$A$ new flashlight cell of $e.m.f.$ $1.5\, V$ gives a current of $15\, A$,when connected directly to an ammeter of resistance $0.04\,\Omega$. The internal resistance of the cell is ........... $\Omega$.

Considering the following circuit,select the correct alternative.

$A$ current of $2.0 \, A$ passes through a cell of $e.m.f.$ $1.5 \, V$ having an internal resistance of $0.15 \, \Omega$. The potential difference measured,in $volts$,across the terminals of the cell will be:

$A$ $12\, V$ lead accumulator is being charged using a $24\, V$ supply with an external resistance of $2\,\Omega$. The internal resistance of the accumulator is $1\,\Omega$. Find the time in which it will store $360\, Wh$ of energy.

If each resistance in the figure is of $9\,\Omega$,then the reading of the ammeter is ............ $A$.

An electric iron draws $5\, A$,a $TV$ set draws $3\, A$,and a refrigerator draws $2\, A$ from a $220\, V$ main line. The three appliances are connected in parallel. If all three are operating at the same time,the fuse used should be of ............. $A$. (in $, A$)
