Q38. Answer  
1. As per given information, we have following network
As we know that 2µF and 1.5µF, both capacitor are in parallel, so we may easily 
calculate their equivalent capacitance.  
In case of parallel  
C=C1+C2 
So, equivalent capacitance of 2µF and 1.5µF 
C= 2µF + 1.5µF = 7/2 µF  
 Now, above network will be converted in following way
4µF 
1.5µF 
2µF 12 V 
4µF 
7/2 µF 12 V 
Now we may see that 4 µF and 7/2 µF,
