MCQ
In the given circuit, bulb will become suddenly bright, if
- ASwitch is closed or opened
- BSwitch is closed
- ✓Switch is opened
- DNone of these
✓
Answer
Correct option: C.
Switch is opened
c
(c)
(c)
Sudden decrease in current due to circuit breaking (opening) will be compensated by sudden induced current flow (as per Lenz's law) and hence sudden brightness.
