The total current supplied to the circuit by the battery is . . . . . . . (in $A$)

Obtain the expression for the equivalent resistance for $3$ resistors connected in parallel and also write the expression of equivalent resistance for connection of $n$ resistors.

What will be the most suitable combination of three resistors $A = 2 \, \Omega$,$B = 4 \, \Omega$,$C = 6 \, \Omega$ so that $\frac{22}{3} \, \Omega$ is the equivalent resistance of the combination?

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 ............... $V$.

$A$ circuit consists of five identical conductors,each of resistance $1 \ \Omega$,as shown in the figure. Two similar conductors are added as indicated by the dotted lines. The ratio of the equivalent resistances before and after the addition is:

Find the equivalent resistance between $P$ and $Q$. (If each wire has a resistance $R$)
