Following figures show different combinations of identical bulb$(s)$ connected to identical battery$(ies)$. Which option is correct regarding the total power dissipated in the circuit?
A uniform wire of resistance $9\, ohm$ is bent in the form of a circle. The effective resistance across the points $A$ and $B$ is ............... $\Omega$
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 ................... $A$
In a potentiometer experiment shown here, for the position $X$ of the jockey $J,$ there occurs a null deflection in the galvanometer. Then the potential difference between points $A$ and $X$ is ................ $V$
Three identical bulbs $B_1, B_2$ and $B_3$ are connected to the mains as shown in figure. If $B_3$ is disconnected from the circuit by opening switch $S$, then incandescence of bulb $B_1$ will
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 .................. $\mathrm{volt}$
Three resistors each of $4\,\Omega $ are connected together to form a network. The equivalent resistance of the network cannot be ............ $\Omega$
