In a series RL circuit, ET = 120 V, R = 40 Ω, and XL = 30 Ω. How much is EL?
dezoksy [38]

Firstly, we will draw

RL series circuit

ET = 120 V, R = 40 Ω, and XL = 30 Ω

Firstly, we will find current

I=\frac{E_T}{R+jX_L}

now, we can plug values

and we get

I=\frac{120}{40+j30}

now, we can find voltage across L

E_L=IjX_L

so, we get

E_L=\frac{120}{40+j30}(j30)

now, we can find absolute value

|E_L|=120\frac{30}{\sqrt{40^2+30^2}  }

|E_L|=120\frac{30}{ 50 }

|E_L|=120\frac{3}{ 5 }

|E_L|=72V...............Answer

adoni [48]

Answer:

S=45m+15

Step-by-step explanation:

we have

E------>the number of sit-ups

m---->  the time in minutes

S----> the number of sit-ups after drinking the sports drink

E=15m+5 ----> equation A

S=3E ----> equation B

substitute the equation A in the equation B

S=3(15m+5)

S=45m+15

What is the area of the trapezoid
irga5000 [103]

The equation for a trapezoid is A = a+b all over 2 times h

So, you would simply substitute.

A=15

B=12

H=8

15+12/2 (8)=

27/2 (8)=

13.5 (8)=
