D
If the Assertion and Reason both are false

E
If Assertion is false but Reason is true
Question 6
4 / -1

Assertion When temperature of cold junction of a thermocouple is lowered, the value of neutral temperature of this thermocouple is raised.
Reason When the difference of temperature of two junctions is raised, more thermo e.m.f. is produced.

A

E
If Assertion is false but Reason is true
Question 9
4 / -1

Assertion If three identical bulbs are connected in series as shown in figure, then on closing the switch bulb C is short circuited and hence illumination of bulbs A and B decreases.
