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

It is c. 216 in³ 
to answer the problem, u must know the formula V=LxWxH (volume= length x width x height)
L=12
W=6
H=3
so, 6x3x12= 216 in³
