Answer:
It wouldn't get any louder then maybe 3db more
Explanation:
There's even a equation if you wanted to check this out but, if they are the same generator same model and all and made the same precise noise it wouldn't increase more then 3db.
Answer:
A. Original energy source is converted to AC power, then transported through conductors to your house.
Explanation:
The correct option is - A. Original energy source is converted to AC power, then transported through conductors to your house.
Well this question is though because we have never seen such a thing ! and to be quite frank when that happens , nothing good comes from it. Black Holes
Answer:
Zeq = 1.80ohms
Vc = 1.11cos4t volts
Explanation:
Impedance of an AC circuit is defined as the opposition to the flow of current across the resistor, capacitor and inductor of an AC circuit. It is expressed mathematically as;
Zeq = √R²+(Xl-Xc)²
Where R is the resistance
Xl is the inductive reactance
Xc is the capacitive reactance
Xl = 2πfL
Source voltage Vs = Vcos2πft
Given Vs = 4 cos (4t)v
Comparing both source voltage to get the frequency f, we have;
2πft = 4t
2πf = 4...(1)
Given L = 0.5H
C = 0.5F
R = 1.0ohms
Xl = 4×0.5 (note that 2πf = 4 from equation 1)
Xl = 2.0ohms
Xc = 1/2πfC
Xc = 1/4(0.5)
Xc = 1/2
Xc = 0.5ohms
To get the impedance Z
Zeq = √1²+(2-0.5)²
Zeq = √1+1.5²
Zeq = √3.25
Zeq = 1.80ohms
The voltage across the capacitor is expressed as Vc = IXc
Since we know Xc = 0.5ohms
We need current I
To get current we use the relationship Vs = IZ
I = Vs/Z =
4 cos (4t)/1.8
I = 2.22cos4t A
Vc = 2.22cos4t × 0.5
Vc = 1.11cos4t volts
