3. Show what equations you are going to use first.

4. Explain your reasons, why do you use these equations?

5. Show what values you are putting into the equations (don't forget units).

6. Show all computational details.

11. Below is a system of six 2-uF capacitors. What potential difference must be applied between points X and Y so that the charge on each plate of each capacitor will have magnitude 18 C? A. 1.5 V B. 3.0 V C. 6.0 V D. 9.0 V E. 18V

Explanation / Answer

For each column of 3 pairs of capacitors,

Ceq1=C1*C2/(C1+C2) = 2*2/2+2 =1 muF

For this three pairs to be in horizontal connetion

Ceq=Ceq1+Ceq1+Ceq1 =3*Ceq = 3 muF

Now,

Q = C*eqV

18 =3*V

V = 6.0 volts
