when the three capacitors r in series,
equivalent capacitance C=9/3 pf=3*10^-12F
voltage supply V=120v
potential difference of each of the three capacitors be E
hence E=V/3=120/3=40v
equivalent capacitance C=9/3 pf=3*10^-12F
voltage supply V=120v
potential difference of each of the three capacitors be E
hence E=V/3=120/3=40v
