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

Brock exercises every day. The function E = 15m + 5 represents the number of sit-ups he can do in m minutes. After drinking a ne

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)=

108.
