So, it's been a little hectic this week. I have been way behind on school because of getting into a car accident and needing doctors and appointments etc etc.. So I need these 4 questions answered.

These are due tonight, as I have to work until late and sadly don't think I will have time to cover the material needed, and finish them. If you are able to provide the correct answers I will give you 50 fg per quesiton.

Once all 4 questions are submitted, I will enter them online. If they are the right answer, I will send you 50 FG per question ** you do not have to do every question. If it is wrong, I will send 15 FG for your time, I know it's not much but these questions should be really easy for some people who know basic AC circuit rules.

I will be catching up on my missed class material after work, so I will post the questions here. Please show your work if possible, it will help me understand more.

Thanks!

Here is the images for each question:



Willing to give someone an extra 100 FG if they do all the question before I get home from work in 5 hours. They should not take long, I just have not covered the material yet

your post is old prob too late now for answers lmk if need
<- residential electrician I can help with any ac circuit problems like this

I still would be willing to pay for help, I am more caught up now just need clarification.

Circuits is all about simplification.

Series resistors add.
Series inductors add.
Parallel capacitors add.

The for the opposites you do the reciprocal of the sum of the reciprocals.

That alone should get you mostly through 1 and 3.

Remember, there are certain rules for dealing with circuits when it comes to DC vs AC current. For DC current, capacitors are open circuits and inductors shorts. This is not the case for alternating current.

For AC, you need to find the impedance and use the rules of AC circuits to find what you're looking for.

Unfortunately it's been a while since circuits for me and don't have time to brush up.

For 3 and 4 there isn't that many answer choices, they are coupled. The question asks for two values.

Voltage = Volts (V)
Current = Amps (A)
Resistance/Impedance = Ohms (Ω)
