In the following circuit composed of identical resistors,across which terminals would you connect a battery in order to dissipate energy in all resistors?

In the circuit shown, if the current through the resistor $R$ is $\frac{1}{5} \, A$, the value of $R$ is (in $\Omega$)

$A$ constant voltage is applied between the two ends of a uniform metallic wire. Some heat is developed in it. The heat developed is doubled if

The equivalent resistance between $x$ and $y$ in the circuit shown is ............. $\Omega$

In the circuit shown in the figure,the ammeter reads a current of ............. $A$.

Consider the circuits shown in the figure. Both the circuits draw the same current from the battery,but the current through $R$ in the second circuit is $\frac{1}{10}$th of the current through $R$ in the first circuit. If $R = 11 \ \Omega$,the value of $R_1$ is ................ $\Omega$.
