A) 5V and 5V
B) 10 V and 5V
C) 10 V and\[-10\text{ }V\]
D) 5 V and \[-5V\]
Correct Answer: C
Solution :
Consider the circuit as shown in figure. It is clear that \[{{V}_{P}}-{{V}_{X}}={{V}_{X}}-{{V}_{O}}\]and \[{{V}_{X}}=0\] \[\therefore \] \[{{V}_{P}}=-{{V}_{Q}}\] Also, \[{{V}_{P}}-{{V}_{Q}}=20\,V\] \[\therefore \] \[{{V}_{P}}=10\,V\]and \[{{V}_{Q}}=-10\,V\]You need to login to perform this action.
