It gets more power5ful case of the coil affect
Answer:
90 degrees
Explanation:
In the attached image we can see, the condition where this condition (|A+B|=|A-B|) is true.
vector A is pointing horizontally to the right, vector B (positive), points up vertically.
Now analyzing the subtraction of vectors A and B = A - B, we have that vector A continues to point to the right (positive) and vector B points down (negative). In this way the magnitudes of both operations sum and subtraction of vectors is equal.
But the angle between the two vectors (A and B) will remain the same and will be 90°.
From the laws of motions:
x = 0.5 at^2 where
x is the displacement
a is the force of gravity (constant = 9.8 m/sec^2)
t is the time taken
Since "a" is constant, therefore:
the displacement is directly proportional to the square of the time.
This means that, increasing the displacement by a factor of 4 would increase the time by a factor of (4)^2 = 16.
Answer:
Inductor should be placed the circuit to raise its power factor.
Explanation:
Inductor:
- It is passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it.
- It has the function of developing electromotive force in the direction that reduces fluctuation when a fluctuating current flows.
Capacitor:
- It is a device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other.
we know that,
Power factor:
cosα = R / Z
cosα = R^2/ (sqrt(R
To increase the power factor, denominator should decrease.
from the equation we can say that, the power factor is inversely proportional to X(L)
Hence X(L) should increase.
Therefore, an inductor is required to be connected.
