What is the reactance of a 25 mF capacitor when the applied frequency is 400 Hz?
LuckyWell [14K]

The Reactance of a Capacitor is t<u>he resistance it has when alternating current (A/C) with a specific frequency (f) passes through it. </u>This is measured in ohms (Ω) and its formula is:


X_{C}=\frac{1}{2\pi fC}   (1)



Where:


X_{C} is the Reactance in ohms (Ω)

f is the frequency of the alternating current in Hertz (Hz)

C is the Capacitance of the Capacitor in Farad (F)



In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.


Note 1mF=1*10^{-3}F=0.001F



Well, with the given data we have to solve (1):


X_{C}=\frac{1}{2\pi(400Hz)(25*10^{-3}F)}    

Then:


XC=0.0159 Ω   This is the Reactance of the Capacitor

Write a Function rule for the table.
Brut [27]

f(x) = x + 3

when x = 0, f(x) = 3

when x = 1, f(x) = 1 + 3 = 4

when x = 2, f(x) = 2 + 3 = 5

when x = 3, f(x) = 3 + 3 = 6

answer is D

f(x) = x + 3

Which equation can be used to show the relationship between the circumference C and a diameter D of a circle
Firlakuza [10]
The diameter is the distance from one side of a circle to the other, if you cross through the center. The circumference is the distance around the circle. The circumference is equal to two time pi time the radius (C=2*pi*r)

SOLVE 3/4 +(1/3/1/6) -(1/2)
jarptica [38.1K]

Answer:9/4

Step-by-step explanation:

3/4 + (1/3/1/6) - (1/2)

3/4 + (1/3 ➗ 1/6) - 1/2

3/4 + (1/3 x 6/1) - 1/2

3/4 + ((1x6)/(3x1)) - 1/2

3/4 + (6/3) - 1/2

3/4 + 2 - 1/2

(3+8-2)/4

9/4
