Question:-
Two capacitors of 3 µF and 6 µF are connected in series with a battery of P. d. 12 V. The P. d. across 3µF and 6µF capacitors respectively will be.
Given that;
To Find:-
The potential difference across 3µF and 6µF capacitors.
Solution:-
Since both the capacitors are 6µF capacitors.
So; the capacitors are connected in series,hence the charge in both capacitors are same.
So; the potential difference across 3µF are;
Since; total potential difference = P.d across 3µF + Potential drop across 6µF .
Hence,8V,4V is the are the potential difference across 3µF and 6µF capacitors.
Given:
Two capacitors of 3 µF and 6 µF are connected in series with a battery of P. d. 12 V.
To find:
Potential difference across the capacitors ?
Calculation:
First we find the net capacitance:
- Net capacitance = (3×6)/(3+6) = 18/9 = 2µF.
Now net charge across the capacitors will be :
So, potential difference across :
- 3µF will be = 24/3 = 8 Volts.
- 6µF will be = 24/6 = 4 Volts.
Hope It Helps.
