| Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). |
| Mark the correct choice as: |
| Assertion [A]: The DC and AC both can be measured by a hot wire instrument. |
| Reason (R): The hot wire instrument is based on the principle of magnetic effect of current. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: C
Solution :
(c) Both AC and DC produce heat, which is proportional to square of the current. The reversal of direction of current in AC is immaterial as far as production of heat is concerned.
