Question
As shown in the figure, a very thin sheet of aluminium is placed in between the plates of the condenser. Then the capacity
- Will increase
- Will decrease
- Remains unchanged
- May increase or decrease
The correct answer is: Remains unchanged
Since aluminum is a metal, therefore field inside this will be zero. Hence it would not affect the field in between the two plates, so capacity 
remains unchanged.
