Current Electricity Charging Discharging Of Capacitors Question 13
If three identical bulbs are connected in series as shown in figure then on closing the switches. Bulb C is short circuited and hence illumination of bulbs A and B decreases. Reason : Voltage on A and B decreases
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason are both false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: D
Solution:
When switch S is closed, bulb C is short circuited, so voltage V distributes only across two bulbs i.e. voltage on Bulb A and B increases as compared previously. Hence illumination of Bulb A and B increases.
