Electrical Circuits Tasks: Step-by-Step Guidance for Beginners in Electrical Engineering

Hello We were given a few tasks with electrical circuits to complete the course. These are probably easy tasks, but when someone sees something like this for the first time, they don't know how to start. Unfortunately, the professor was driving the theory itself because he said that we should learn electrical circuits ourselves.

I am not asking you to solve these problems !!! I would only ask you to show me the way if possible. (eg listing in bullet points what needs to be done or something). If I don't know something, then I'll ask

Please help I really want to learn this because I plan to combine my major (programming) with electronics.

Here are the tasks:




Here I tried to do something (the first was done, but I don't know if it is right, and I got stuck with the second because I don't know what to do next):

Don't count on it. Puki, you won't take it yourself, I won't help you.

When I look at these problems, you should solve them based on your theoretical knowledge. Halfway, it's not even much to count ...
Task 1 - password key: voltage divider and current divider.
Task 2 - read about alternating current circuits, because you can't touch it with a hindrance.
Task 3 - time constant. End of the task. You know this term, this task is very easy.
Task 4 - as above, but for inductance.
Task 5 - to read: wattmeter, active power
Exercise 6 - to read: the rectifier.

Thank you very much. That's what I meant At least I know where to start.

Task 1 to be checked (current and voltage divider).



Task 3 (I do not know if it is good - I have no idea how to determine after what time the steady state will occur in this system and what will be the value of the overvoltage Ul).



Task 4 (I don't know if it's good - I have no idea how to count after what time and to what value the capacitor will be charged)
