Answer:
The inductance of the inductor is 0.051H
Explanation:
From Ohm's law;
V = IR .................. 1
The inductor has its internal resistance referred to as the inductive reactance, X
, which is the resistance to the flow of current through the inductor.
From equation 1;
V = IX
X
=
................ 2
Given that; V = 240V, f = 50Hz,
=
, I = 15A, so that;
From equation 2,
X
= 
= 16Ω
To determine the inductance of the inductor,
X
= 2
fL
L = 
= 
= 0.05091
The inductance of the inductor is 0.051H.
Answer:
It is true that the sampling distribution of the proportions is approximately a normal distribution.
Explanation:
Solution
Given that:
N = 50
P= 0.8
Thus
p ^ =√p(1-p)/n
p ^=√0.8 (1-0.8)/50
p ^= 0.0566
Therefore,we conclude that the sampling distribution of the proportions is approximately a normal distribution.
