How can they say voltage across R is 2 V? The voltage across R should be a combination of 12 V and 2 V isn't it?

I think as Galvanometer is connected to that circuit ...... and it shows zero deflection that means no current is flowing through Galvanometer.......... and hence circuit is short circuited. So it should be 2 V

http://prntscr.com/3egt02 and heres the pic i was to lazy to draw a circuit >.< , And btw thanks fo the ban doe xP

aravindg · Answer

If circuit is short circuited then only voltage across R should be 12 isn't it?

experimentx · Answer

the Potential difference between those two points is same as the PD between the power supply at the left.

aravindg · Answer

So that will be 12 V?

cybershadow · Answer

Yeah It will be 12V  sorry i thought 2 V was on the short-circuited side

experimentx · Answer

woops!! I sometimes forget between left and right ...

experimentx · Answer

2V of course ... I should have said ... the two points that you are going to measure is same as the the points between that power source A.

cybershadow · Answer

Ah jeez now i m confused >.< care to explain how come it is 2 V?

aravindg · Answer

Yeah I am also confused.

experimentx · Answer

could you draw the figure ... i mean copy that fig?
