Express your answer using two significant figures. Find the charge on each capacitor. Express your answers using two significant figures separated by a comma. Find the total energy stored in the network. Express your answer using two significant figures. For the capacitor network shown in the figure below(Fjgure 1), the potential difference across ab is 46 V. Find the energy stored in each capacitor. Express your answers using two significant figures separated by a comma. Find the potential difference across each capacitor. Express your answers using two significant figures separated by a comma. A 13.0 mu F capacitor is connected to a power supply that keeps a constant potential difference of 24.0V across the plates. A piece of material having a dielectric constant of 3.75 is placed between the plates, completely filling the space between them. How much energy is stored in the capacitor before the dielectric is inserted? How much energy is stored in the capacitor after the dielectric is inserted? By how much did the energy change during the insertion?Explanation / Answer
1)since capacitors in series
Q is same
q/150+Q/120=46
Q=3066.67.nC
2) charge on each capacitor also same Q=3066.67.nC
3)energy stored is Q^2/2*c
=Q^/2*c1 +Q^2/2*c2 is total energy =70533.48 nJ
energy of capacitor 1
is Q^2/2*c1=31348.216 nJ
and of second one is 39185.27 nJ
voltage of first part is =Q/c1=3066.67/150=20.44 V
for part 2 Q/c2=3066.67/120=25.55
