two capacitors of 6 microfarad and 12 microsar 8 are in series across a 180 volt dc supply calculate the potential difference across each capacitor?
Answers
Answer:As per the question, the capacitors are connected in series.
It is given that c1=6 and c2=12
The supply voltage v = 180 volts.
The net capacitance of the circuit is calculated as -
1/c=1/c1+1/c2
which gives us 4×10⁻⁶
The charge flowing across the circuit is calculated as -
q=cv
=4×10⁻⁶×180 volts=72×10⁻⁵
We know that charge remains the same during series connection of capacitors.
Hence, the charge on each capacitor is 72×10⁻⁵
