The wiring of a house has a resistance of $6\,\Omega$. $A$ $100\,W$ bulb is glowing. If a geyser of $1000\,W$ is switched on,the change in potential drop across the bulb is nearly .................. $V$.

In steady state, the potential difference across the capacitor is $10\, V$. Each resistance is of $3\, \Omega$. The cell is ideal. The $emf$ of the cell is ............. $V$.

In the circuit shown in the figure,the currents in different branches and the value of one resistor are given. Then,the potential at point $B$ with respect to point $A$ is $.......V$.

$A$ wire of cross-section area $A$,length $L_1$,resistivity $\rho_1$ and temperature coefficient of resistivity $\alpha_1$ is connected to a second wire of length $L_2$,resistivity $\rho_2$,temperature coefficient of resistivity $\alpha_2$ and the same area $A$,so that the wires carry the same current. The total resistance $R$ is independent of temperature for small temperature changes if (Thermal expansion effect is negligible):

The current flowing through the circuit shown in the figure is ........... $A$.

Find the current through the $2\,\Omega$ resistance in the given circuit. (in $A$)
