Calculate the potential difference between points a and b in the figure

(a) Calculate the potential difference between points a and b in the figure and (b) identify which point is at the higher potential.

If there is no current through the 10-ohm resistor, why is there a current through the 4v battery ???

🙏
For calculating v why did u took the shorter path
Why not the longer one(containing 12v cell)

[md.ashrafulislamsami]

why did you ignore the 10 ohm resistor?

[albinsiby]

why will current not flow through the whole circuit when a and b are connected???

[mohammadjunaidkhan]

Vab =( potential at point a)- (potential at point b) and its value comes out to be -4 volt ;
negative answer means potential at point a< potential at point b. then how come potential at point a is higher than at point b as u said?

Your videos are saving my a** currently. Words don't do my appreciation justice; thank you for taking the time to do all of this.

Thank you! have midterm on Tuesday, this is super helpful

If there is no current through the 10 ohmes resistance that means there is no potential difference to move the electrons
how there is 4V ??

[Munyaradzi_Jacob]

Thank you for the help.. But i want to ask about a circuit without e.m.f sources.. Which only contains resistors 3 in parallel and another one in series to the three given the power dissipated in one of the resistors

[itssimple]

a will be at lower potential as it comes negative voltage but you mentioned alter

[johnkim]

Why is there no current in 10 resistor

[enesakturan]

Where is the source of this question? Can you pls say it

[RobotsSale]

how can you have a 12volt and 4volt connected to the same circuit
