152611 The temperature of the cold junction of a thermocouple is $0^{0} \mathrm{C}$ and the temperature of the hot junction is $\mathrm{T}^{\circ} \mathrm{C}$. The relation for the thermo emf is given by, $\mathrm{E}=\mathrm{AT}-\frac{1}{2} \mathrm{BT}^{2}$ (When $A=16$ and $B=0.08$ ). The temperature of inversion will be :

1 $500^{\circ} \mathrm{C}$
2 $460^{\circ} \mathrm{C}$
3 $600 \mathrm{C}$
4 $400^{\circ} \mathrm{C}$

152606 Assertion: In a simple battery circuit, the point of the lowest potential is negative terminal of the battery.
Reason: The current flows towards the point of the higher potential, as it does in such a circuit from the negative to the positive terminal.

1 If both Assertion and Reason are correct and reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion
3 If Assertion is correct but Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
