41.
As the diameter of a wire is doubled, the resistance becomes
Answer: Option
Explanation:
Since diameter is doubled, area of cross-section becomes four times and resistance is inversely proportional to area of cross-section.
42.
A series resonant circuit has R = 10 Ω, L = 1 μH and C = 1 mF. If R is increased to 20 Ω the resonant frequency
Answer: Option
Explanation:
fr depends only on L and C.
43.
Assertion (A): Two terminal black boxes of R and C can be identified by plotting their static V-I characteristics.
Reason (R): The V-I characteristic of resistance is a straight line of slope R passing through origin.
Answer: Option
Explanation:
A is wrong because static V-I characteristics do not identify the elements.
44.
