In a parallel circuit, ET = 240 V, R = 47 kΩ, and XL = 50 kΩ. What is the reactive power?
Fittoniya [83]

Answer:

Reactive power is 1.152 VARs

Step-by-step explanation:

We are given that in a parallel circuit,E_{T}=240V,R=47kΩ and X_{L}=50kΩ.

reactive power means the dissipating power resulting from inductive and capacitive loads measured in volt-amperes reactive(VAR).Since our circuit has inductor only, reactive power will be power dissipated from inductor.

Current through inductor=\frac{E_{T}}{X_{L}} =\frac{240}{50}=4.8milli amps=0.0048 A

Reactive power = (current flowing through inductor)X (Voltage across inductor)

Hence reactive power = 0.0048 X 240=1.152 VARs

Y= Mx+B. Solve for M
s344n2d4d5 [400]

You said that                             Y            = Mx + B

Subtract  B  from each side:     Y - B       =  Mx

Divide each side by 'x' :           (Y - B) / x  =  M

X-12y=-210 and x-6=90
m_a_m_a [10]

Answer:

x = -30

y = -20

Step-by-step explanation:

x - 12y = 210..... (I)

x - 6y = 90..... (II)

Subtract equation (II) from (I)

- 12y - (-6y) = 210 - 90

-12y + 6y = 120

-6y = 120

Divide through by -6y

Therefore, y = -20

Substitute y = -20 in equation (II)

x -6 (-20) = 90

x + 120 = 90

x = 90 - 120

x = -30

Hope that helped
