The minimum number of condensers each of capacitance of 2µF, in order to obtain resultant capacitance of 5µF will be-
Text Solution
Verified by ExpertsThe correct answer is:
A
If two capacitors will be in series and two capacitors will be in parallel as shown in figure then, equivalent capacitance will 
.
Let see AB and BC capacitors are in series
So, equivalent capacitance 
of it 
{in series 
DE and GF capacitors are in parallel,
So, equivalent capacitance 
of it 
{in parallel, 
Now, X and Y capacitors are in parallel then,
microfarad.
Hence, minimum number of capacitors
