The current $I$ flowing through the given circuit will be $.....A$.

The equivalent resistance between $A$ and $B$ is $:-$

In the network shown in the figure,the equivalent resistance between points $X$ and $Y$ will be . . . . . . $\Omega$. The value of each resistor is $2 \Omega$.

Four wires of equal length and of resistances $10 \ \Omega$ each are connected in the form of a square. The equivalent resistance between two opposite corners of the square is ............. $\Omega$. (in $\Omega$)

Three resistances of $4\,\Omega$ each are connected in the form of an equilateral triangle. The effective resistance between any two corners is:

$A$ $100\, W$ bulb $B_1$ and two $60\, W$ bulbs $B_2$ and $B_3$ are connected to a $220\, V$ source,as shown in the figure. If $P_1, P_2$,and $P_3$ are the output powers of the bulbs $B_1, B_2$,and $B_3$ respectively,then:
