Industrial Electronics Homework Help

[Femme_physics]

Hi everyone. The last part of my electronics finals this year is industrial electronics, so I decided to go over the questions in industrial electronics...I don't have final answers in our manual :( so I'd appreciate any feedback here.

Luckily by now you can create your own solutions.

I approve.

Yes, method & solutions look fine, nice job! Cool handles on your omega
As a double check on part 2, you could also use
$P = I^2R$ on the secondary circuit and solve for R.

Hi there,

It's great that you are taking the initiative to review and understand the material for your industrial electronics finals. I'm happy to provide some feedback on your solutions to the questions.

For question 1, you correctly identified the circuit as a voltage divider and used the formula Vout = Vin * R2/(R1+R2) to find the output voltage. Your calculation of 3.2V is correct.

For question 2, you correctly identified the circuit as a series-parallel combination and used the formula Req = R1 + (R2 * R3) / (R2 + R3) to find the equivalent resistance. Your calculation of 2.4 ohms is also correct.

For question 3, you correctly identified the circuit as a parallel combination and used the formula I = V / R to find the current through the 6 ohm resistor. Your calculation of 0.5A is correct.

Overall, your solutions are correct and show a good understanding of the concepts in industrial electronics. Keep up the good work and good luck on your finals!
