In a parallel circuit, et = 240 v, r = 5.6 kω, and xl = 3.6 kω. what is p?

Real power,P is 10.286 Watts

Step-by-step explanation:

We are given that in a parallel circuit, ,R=5.6kΩ and =3.6kΩ

We are asked to find P which means real power, that is power due to resistance.

Let us find current through resistor first.

That is milli Amps=0.04286 A

Hence

                    =240X0.04286=10.286 Watts

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
