Could someone please help me in finding the potential difference Vab?
Thanks!
Finding Potential Difference Vab in Parallel Circuits
AI Thread Summary
To find the potential difference Vab in parallel circuits, it's essential to remember that the voltage across all parallel elements is the same. The current in each branch must be calculated, which will then allow for determining the potential difference. Once the voltages Va and Vb are established, Vab can be calculated. Additionally, it's noted that the original post was made in the wrong forum, as there are dedicated homework forums for such queries. Properly identifying the right platform for questions can enhance the likelihood of receiving accurate assistance.

You've posted this in the wrong forum. There are homework forums for that. You only need to work out the current in each parallel branch, bearing in mind that the voltage across parallel elements are the same. Then with the current, you can find the potential difference and hence Va and Vb. Then with both Va and Vb you can find Vab.

thanks mate!
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...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
The answer to this question is statements (ii) and (iv) are correct.
(i) This is FALSE because the speed of water in the tap is greater than speed at the water surface
(ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not?
(iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
