The total power dissipated in Watts in the circuit shown here is

If three bulbs $60\,W$,$100\,W$ and $200\,W$ are connected in parallel,then

In an experiment, a graph was plotted of the potential difference $V$ between the terminals of a cell against the circuit current $i$ by varying the load rheostat. The internal conductance of the cell is given by:

Ratio of thermal energy released in two resistors $R$ and $3R$ connected in parallel in an electric circuit is:

In the following circuit, a power of $50 \ W$ is absorbed in the section $AB$ of the circuit. The value of resistance '$X$' is (in $\Omega$)

The battery in the diagram is to be charged by the generator $G$. The generator has a terminal voltage of $120 \ V$ when the charging current is $10 \ A$. The battery has an $emf$ of $100 \ V$ and an internal resistance of $1 \ \Omega$. In order to charge the battery at $10 \ A$ charging current,the resistance $R$ should be set at ................ $\Omega$.
