Q. 33.7( 3 Votes )
If the capacitors in the previous question are joined in parallel, the capacitance and the breakdown voltage of the combination will be
A. 2C and 2V
B. C and 2V
C. 2C and V
D. C and V
Answer :
Given:
Two capacitors of capacitance C each and breakdown voltage V connected in parallel
Explanation:
The general formula for effective capacitance of a series combination of n capacitors is given by
The equivalent capacitance of two capacitors connected in parallel are given by
Where
C1 is the capacitance of the capacitor C1
C2 is the capacitance of the capacitor C2
Here C1=C2=C
Putting the values in the above formula, we get
∴ Ceq=C+C=2C
Since, potential difference across capacitors in parallel are equal
Therefore voltage across the system is equal to the voltage across a single capacitor.
Therefore, breakdown voltage of the combination =V
