In the following circuit, the battery has an emf of $2\mathrm{V}$ and an internal resistance of $\frac{2}{3}\ \Omega$. The power consumption in the entire circuit is$..... W.$
$2$
$3$
$4$
$5$
The amount of heat produced in a resistor when a current is passed through it can be found using
he power dissipated in the circuit shown in the figure is $30\,W$. The value of $R$ is ............. $\Omega$
A bulb of $100\, W$ is connected in parallel with an ideal inductance of $1\, H$. This arrangement is connected to a $90\,V$ battery through a switch. On pressing the switch, the
Ratio of thermal energy released in two resistor $R$ and $3 R$ connected in parallel in an electric circuit is :
If power in $3\,\Omega $ is $27\,W$ then what is the power in $2\,\Omega $ ................ $\mathrm{W}$
