Answer:
Explanation:
Given that
Vrms= 60 V
Vf= 0.7 V
We know that peak value of AC voltage given as
Now by putting the values
The output voltage of the DC current given as
Therefore output voltage of the DC current is 84.15 V.
Answer:
The correct answer is letter "B": heritable variation among individuals in the population.
Explanation:
According to the natural selection theory, greatly spread after Charles Darwin's research, four (4) conditions are needed for it to take place: <em>reproductions, heredity, variation in organisms, </em>and <em>variation among individuals in the population</em>. Only in the case the four conditions are met, natural selection occurs.
Answer:
Explanation:
The concept of amperes law is applied;
Given the current density vector in the medium is J,
the electric flux density vector is D,
and the magnetic flux density vector is B. The line integral of the magnetic field intensity H
considering the orientation of the contour is adopted according to ampere law;
deta x B = Jc + JD
delta x B = Jc + partial differential D/partial differential t
where Jc = conduction current density
JD = displacement current density
Answer:
<u>Eo = A/[-nB/A]^(1/n-1) + B/[-nB/A]^(n/n-1)</u>
Explanation:
<u>Step 1.</u>
Taking derivative of the equation with respect to 'r' we get:
d/dr(EN) = - A/r² - nB/r^(n+1)
Setting this equation to zero:
<u>Step 2.</u>
Solving for r:
- A/r² - nB/r^(n+1) = 0
A/r² + nB/r^(n+1) = 0
Ar^(n+1) + nBr² = 0
Ar^(n+1) = - nBr²
[r^(n+1)]/r² = - nB/A
r^(n+1-2) = - nB/A
r^(n-1) = - nB/A
Taking power 1/(n-1) on both sides:
r = [-nB/A]^(1/n-1)
This is the value of ro:
ro = [-nB/A]^(1/n-1)
<u>Step 3.</u>
Substituting value of ro in eqn we get value of Eo
<u>Eo = A/[-nB/A]^(1/n-1) + B/[-nB/A]^(n/n-1)</u>
Answer: If saturation effects are ignored, the magnetization curve of Fig. 7.27 becomes a straight line with a constant slope of 150 volts per ampere of field current.
