AI Thread Summary
To calculate impedance from power figures expressed in watts, one must understand the relationship between power, voltage, and current. The discussion highlights confusion stemming from unclear images and inadequate post formatting, which hinder effective communication. Participants express frustration over the lack of clarity in the original post, emphasizing the need for better presentation of information. The conversation also touches on the importance of adhering to forum guidelines to facilitate assistance. Overall, clear communication and proper formatting are essential for resolving technical inquiries effectively.

How do I figure out the impedance if the figures are shown in watts? I am used to seeing the values in rectangular form.

We can't answer a question based on a picture we can't see. The picture is out of focus and cuts half of the text.

It baffles me how often people can't take the time to write an acceptable post.

I can picture you waving your fist in the air, haha calm down!

Picture looks ok to me pal, you can see the power figures in place instead of the usual Z impedance. I was saying I have never came across this before.

Please read this before posting. You aren't getting any help by being passive aggressive.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
