I know that T = RC
I've tried different combinations of R (not really sure what Req to take) but none of them worked. Any one can show me the right way ?

AI Thread Summary
The time constant in an RC circuit is calculated using the formula T = RC. Users are encouraged to determine the correct equivalent resistance (Req) for accurate calculations. The Thevenin equivalent method is suggested as a reliable approach to simplify the circuit analysis. One participant successfully applied this method after initial difficulties with different resistance combinations. Utilizing the Thevenin equivalent can enhance understanding and accuracy in calculating the time constant.

Have you tried taking the Thevenin equivalent for point a to b?

No I haven't and it was suggested on another forum and it worked. Thank you :)
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.
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...
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...
