In a series RL circuit, ET = 120 V, R = 40 Ω, and XL = 30 Ω. What is ER?

Delvig [45]

Answer:

The voltage across resistor is $E_{R}=96V$

Step-by-step explanation:

We are given with Voltage across terminals of a series RL circuit, $E_{T}=120V$

And Resistance R=40Ω

And inductor reactance $X_{L}=30$ Ω

Since Resistor and inductor are in series, same current flows through both.

And that current, I = $\frac{E_{T}} {Z}$

$=\frac{120}{\sqrt{40^{2}+30^{2}}}= \frac{120}{\sqrt{2500}}$

= $\frac{120}{50}=2.4A$

Therefore voltage across resistor, $E_{R}=IR=2.4X40=96V$

What is the sum of 1 2/8 + 2 5/8

SVEN [57.7K]

Hey there!

1 + 2 = 3

2/8 + 5/8 . . .

= 7/8 (denominator stays the same)

3 + 7/8 = 3 7/8

The sum of the numbers 1 2/8 and 2 5/8 is 3 7/8.

1 2/8 + 2 5/8 = 3 7/8.

Hope this helps you.
Have a great day!
