152655 A circular wire has current density $J=\left(2 \times 10^{10} \frac{A}{\mathrm{~m}^{2}}\right) \mathbf{r}^{2}$, where $\mathbf{r}$ is the radial distance, out of the wire radius is $2 \mathrm{~mm}$. The end-to-end potential applied to the wire is $50 \mathrm{~V}$. How much energy (in joule) is converted to thermal energy in 100s?
152656 The filament of an electric kettle is made up of three sections of equal resistances. These sections are connected in parallel and the water begins to boil in 9 minutes. If these resistance are connected in series, then the time taken by the same mass of water in the kettle to bail is
152657 Two metallic wires $A$ and $B$ are made using copper. The radius of wire $A$ is $r$ while its length is $l$. A dc voltage $V$ is applied across the wire $A$, causing power dissipation, $P$. The radius of wire $B$ is $2 r$ and its length is $2 l$ and the same de voltage $V$ is applied across it causing power dissipation $P_{l}$. Which one of the following is the correct relationship between $P$ and $\boldsymbol{P}_{1}$ ?
