Answer: C :- 1H
Step-by-step explanation:
we can use the formula for inductance (L) of an inductor with an iron core:
L = N^2/ R
wher
N = Number of turns (10 turns in this case)
R = Reluctance of the core (given as 100 AT/Wb)
Put the values and calculate the inductance (L):
L= 10^2/100
L= 100/100
= 1
So, the inductance of the coil is 1 Henry (1H).
