Question

In the diagram below, V=100v

C1=12x10^-6f

C2=24x10^-6f

R=10 ohms.

Initially, C1 and C2 are uncharged, and all switches are open.

A) First, switch S1 is closed. Determine the charge on C1 when equilibrium is reached.

B) S1 is opened and S2 is closed. Determine the charge on C1 when equilibrium is reached again.

C) For the equilibrium condition of part (B), determine the voltage across C1.

D) S2 remains closed, and now S1 is also closed. How much additional charge flows from the battery?

*Algebra based class

*Please explain answer

In the diagram below, V = 100 volts; Cl = 12 pf; C2 = 24 R =10 0. Initially, Cl and C2 are uncharged, and all switches are open.

a.C*V=1.2 mC

b.as both are in parallel,

they will have same voltage across them.

total charge=1.2 mC

let voltage be V.

then (12*V+24*V)*10^(-6)=1.2*10^(-3)

V=33.33 volts

so charge on C1=33.33*12*10^(-6)=0.4 mC

c)voltage=33.3 volts

d)after they reach equilibrium,

voltage across C1=voltage across C2=100 volts

so net charge=C1*V+C2*V=3.6 mC

so additional charge=2.4 mC
