Inside $a$ super conducting ring six identical resistors each of resistance $R$ are connected as shown in figure. Imagine a battery of $emf$ $E$ between the point $0$ and $1$, with its positive terminal connected with $O.$
The resistors of resistances $2$ $\Omega$, $4$ $\Omega$ and $8$ $\Omega$ are connected in parallel, then the equivalent resistance of the combination will be
A steel wire has a resistance twice that of an aluminium wire. Both of them are connected with a constant voltage supply. More heat will be dissipated in
