An electrician charges a set fee of $50 for every house call and then charges an additional hourly rate. One day, the electricia

Serhud [2]

Answer:

$50+5t=C$

Step-by-step explanation:

Suppose the electrician spends t hours at the house working.

Amount charged for every house call by electrician = $50

The electrician earned a total of $400 for a 5 hour job.

Also, C denotes total cost of the electrician's services.

So, the equation for C in terms of t is given below.

$50+5t=C$

Here, $C=400$

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, $E_{R}=IR=2.4X40=96V$
