Three resistances of magnitude $2\,\Omega$,$3\,\Omega$,and $5\,\Omega$ are connected in parallel to a battery of $10\,V$ and of negligible resistance. The potential difference across the $3\,\Omega$ resistance will be ............... $V$.

Lamps used for household lighting are connected in

$10$ wires (same length,same area,same material) are connected in parallel and each has $1 \ \Omega$ resistance,then the equivalent resistance will be .............. $\Omega$.

$A$ network of resistors is connected to a $16\; V$ battery with internal resistance of $1\; \Omega$ as shown in Figure:
$(a)$ Compute the equivalent resistance of the network.
$(b)$ Obtain the current in each resistor.
$(c)$ Obtain the voltage drops $V_{A B}, V_{B C}$ and $V_{C D}$.

What is the equivalent resistance between $A$ and $B$?

The figure shows a tetrahedron where each edge has a resistance $r$. If a battery is connected between any two vertices of the tetrahedron,identify the correct statement$(s)$.
