The reading of the ammeter in the following figure will be: (in $\text{A}$)

Each element in the finite chain of resistors shown in the figure is $1\,\Omega $. $A$ current of $1\, A$ flows through the final element. Then what is the potential difference $V$ across input terminals of the chain (in $,V$)?

In the given circuit,the resistance of the voltmeter is $10,000\, \Omega$ and the resistance of the ammeter is $20\, \Omega$. The ammeter reading is $0.1\, \text{A}$. If the voltmeter reading is $12\, \text{V}$,then the value of $R$ is ............ $\Omega$.

In the circuit,$R_{1} = R_{2} = R$. The value of $E$ and $R_{1}$ are $\ldots \ldots \ldots$ ($E$ = $EMF$,$R_{1}$ = resistance).

The magnitude and direction of the current in the circuit shown 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.
