17. In the portion of a circuit shown, if the heat generated in $$5\Omega$$ resistance is 10 calories per second, then heat generated by the $$4\Omega$$resistance, in calories per second, is _________.



$$\left ( 2I \right )^{2}\times 5=10$$

$$I_{2}=10\setminus 5\chi 4$$

$$I^{2}\chi 4=0.5\chi 4=2cal\setminus sec$$
