Why do you say that?Have you considered that there is possibly a typo error in the question?
The answers are given.do you know about ratios? If not then you must say so,then I will tear it apart to help you understand.I need help to understand the solution to this question:
Sorry, my mistake.Why do you say that?
The question implies that the particular value of R doesn't matter. So pick a value of R that makes things easy for you.Will you please, I need help to understand the solution to this question:

The examiner say that the answer is 11 Volt. I don't know why. Please help. Thanks
The absolute value is 11V. Problem is poorly worded.Then the potential difference between a and d =(6/R) . (11R/6) = 11 V.
You are correct. The exam question was written by an idiot.Isn't it -3V? No-one said where the power supply was connected. It could quite feasibly be between b and c, and no-one said that a and d were connected to anything at all.
I wouldn't say that. The circuit in question is hypothetical don't over analyze it. Besides what if the current is AC.he exam question was written by an idiot.
No need to guess -- the resistance of each resistor is R.Why doesn't the question say the resistor values?
Is the student supposed to guess that they are all the same?
This exam question is so simple that I did it without writing down anything.
It's 3 V because that is the given condition. If you get to question whether it is -3 V instead, then you can just as validly question whether it is -98.2 V instead. It is a GIVEN that it is 3 V.Isn't it -3V? No-one said where the power supply was connected. It could quite feasibly be between b and c, and no-one said that a and d were connected to anything at all.
It would have the same issue regarding the relative polarity of the two voltages in question.I wouldn't say that. The circuit in question is hypothetical don't over analyze it. Besides what if the current is AC.
Even with AC current?It would have the same issue regarding the relative polarity of the two voltages in question.
