Current Electricity Charging Discharging Of Capacitors Question 728
Question: In the circuit shown in the figure, if potential at point A is taken to be zero, the potential at point B is
Options:
A) -1V
B) +2V
C) -2V
D) +1V
Show Answer
Answer:
Correct Answer: D
Solution:
[d] Current from D to C $ ~=1A $
$ \
Therefore V _{D}-V _{C}=2\times 1=2V $
$ V _{A}=0\text{ }\
Therefore V _{C}=1V,\
Therefore V _{D}-V _{C}=2 $
$ \Rightarrow V _{D}-1=2\text{ }\
Therefore V _{D}=3V $
$ \
Therefore V _{D}-V _{B}=2\text{ }\
Therefore 3-V _{B}\text{=2 }\
Therefore V _{B}=1V $
