Both the number of turns and the core length of an inductive coil are doubled. Its self-inductance will be
A. unaffected
B. doubled
C. halved
D. quadrupled
Answer:B
Both the number of turns and the core length of an inductive coil are doubled. Its self-inductance will be
A. unaffected B. doubled C. halved D. quadrupled
Explanation: When both the number of turns and the core length of an inductive coil are doubled, then the self-inductance of an inductive coil will get doubled.
