The potential difference (VA - VB) between the points A and B in the given figure is
-3 V
+3 V
+6 V
+9 V
As we discussed in
Potential difference -
The voltage accross the terminals of a cell when it is supplying current to external resistance is known as Potential Difference .
- wherein
= 2x2+3+1x2=9V
Option 1)
-3 V
This option is incorrect.
Option 2)
+3 V
This option is incorrect.
Option 3)
+6 V
This option is incorrect.
Option 4)
+9 V
This option is correct.
