$A$ dry cell has an $e.m.f.$ of $1.5\, V$ and an internal resistance of $0.05\,\Omega$. The maximum current obtainable from this cell for a very short time interval is ................... $A$.

If the ammeter in the given circuit reads $2\, A$,the resistance $R$ is ............ $\Omega$.

In the circuit shown,the power developed in the $6\,\Omega$ resistor is $6\,W$. The power developed in the $4\,\Omega$ resistor is .............. $W$.

$50\,\Omega$ and $100\,\Omega$ resistors are connected in series. This combination is connected to a battery of $2.4\,V$. When a voltmeter of $100\,\Omega$ resistance is connected across the $100\,\Omega$ resistor,the reading of the voltmeter will be ............. $V$.

In the following circuit,the $5 \, \Omega$ resistor develops $45 \, J/s$ due to the current flowing through it. The power developed per second across the $12 \, \Omega$ resistor is ............. $W$.

In the circuit shown below, a student performing Ohm's law experiment accidentally connects the voltmeter and the ammeter as shown. The reading in the voltmeter will be close to .......... $V$.
