For a given thermocouple neutral temperature
1 is a constant
2 depends on cold junction
3 depends on inverse temperature
4 double that of cold junction temperature
Explanation:
A The temperature of the hot junction at which the thermocouple emf produced in the thermocouple becomes max. is called neutral temperature. For a given thermocouple natural temperature has a fixed value.

Inversion temperature for a thermocouple is the temperature at which thermo emf
1 increases
2 remains unchanged
3 changes erratically
4 reverses in sign
Explanation:
D Inversion temperature for a thermocouple is the temperature at which thermo emf changes its sign.

The specific resistance of a conductor increases with
1 Increase in temperature
2 Increase in cross-sectional area
3 Decrease in length
4 Decrease in cross-sectional area
Explanation:
A Specific Resistance (Resistivity) of a conductor increase with increase in temperature but its does not depends on its geometry because it is the internal property of material.

A capacitor is connected to a cell of emf $E$ and some internal resistance $r$. The potential difference across the
1 cell is $\mathrm{E}$
2 cell is $\lt$ E
3 capacitor is $\lt\mathrm{E}$
4 capacitor is $>E$
Explanation:
A As we know, when a capacitor is fully charged, then the current is drawn by it. when no current flow in the circuit, potential difference across the cells emf of cell $=$ potential difference across the capacitor.
