Find the equivalent resistance in a circuit

AI Thread Summary
The discussion revolves around calculating the equivalent resistance in a circuit with multiple resistors. Two 4 Ohm resistors are identified as being in series, resulting in an 8 Ohm total resistance. The remaining resistors, 2 Ohm, 4 Ohm, and 2 Ohm, are confirmed to be in series as they carry the same current. This leads to the conclusion that the two 8 Ohm resistors are in parallel, yielding a net resistance of 4 Ohms. The solution can be verified using Kirchhoff's law to confirm that the current in both branches is the same.

The Attempt at a Solution



I know the two 4 Ohm resistors (on the same wire) are in series and thus add to 8 Ohms. However, I do not know where to go from here. When the resistors are in a box, with one on each side, are they in series? Or are they two parallels?

Thanks!

I believe the 2,4,2 ohm resistors are all in series since the same current flows through them.

So this would leave me with two parallel resistors of 8 Ohms each? And finding the equivalent resistance would give us 4 Ohms?

If you (or someone else) can confirm this, it would be greatly appreciated!
 
yep. 8 ohm 8ohm are in parrellel giving 4 ohm net resistance. can be veryfied using kirhoff's law to show current in both branches are the same.

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 'Correct statement about a reservoir with an outlet pipe'

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...
