Resistors of $1\, \Omega$, $2\, \Omega$, and $3\, \Omega$ are connected in the form of a triangle. If a $1.5\, V$ cell of negligible internal resistance is connected across the $3\, \Omega$ resistor, the current flowing through this resistance will be ................ $A$.

Twelve wires of equal length and equal cross-sectional area form a cube. If the resistance of each wire is $R$,then the effective resistance between the two ends of a diagonal is:

Two electric bulbs with ratings $25\, W - 220\, V$ and $100\, W - 220\, V$ are connected in series to a $440\, V$ supply. Which bulb will fuse?

The ammeter reading in the following circuit will be .............. $A$.

Resistances $R_1$ and $R_2$,each $60\,\Omega$,are connected in series as shown in the figure. The potential difference between $A$ and $B$ is maintained at $120\,V$. What will be the reading of the voltmeter connected between points $C$ and $D$ if the resistance of the voltmeter is $120\,\Omega$?

Calculate the amount of charge flowing in $2$ minutes in a wire of resistance $10\,\Omega$ when a potential difference of $20\,V$ is applied between its ends.
