Each of the resistances in the network shown in the figure is equal to $R$. The resistance between the terminals $A$ and $B$ is

In the following circuit,if $V_A - V_B = 6\,V$,then the value of resistance $R$ (in $\Omega$) is ............... $\Omega$.

In the given circuit,the current in $8 \Omega$ resistance is $1.5 \text{ A}$. The total current $(I)$ flowing in the circuit is (in $\text{ A}$)

Two electric bulbs whose resistances are in the ratio of $1 : 2$ are connected in parallel to a constant voltage source. The powers dissipated in them have the ratio:

In the given circuit, the current flowing through the resistance $20 \, \Omega$ is $0.3 \, A$, while the ammeter reads $0.8 \, A$. What is the value of $R_1$ in $\Omega$?

In the figure shown, if the internal resistance of the battery is $1\, \Omega$, the reading of the ammeter will be ................. $A$.
