Responses/submit 7dep,anzar A parallel-plate capacitor with capacitance Co stores charge of magnitude Qo on plates of area Ao separated by distance do. The potential difference across the plates is AVo HINT If the capacitor is attached to a battery and the charge is quadrupled to 4Qa, what are the ratios e nd Co (a) Cnew Co (b) ew nter a number Cnew A second capacitor is identical to the first capacitor except the plate area is quadrupled to 4Ap- If given a charge of Qor what are the ratios and new Co (c) (d ew A third capacitor is identical to the first capacitor, except the distance between the plates is quadrupled to 4do. If the third capacitor is then given a cha of Qo, what are the ratios and Cnew AVnew Co

Explanation / Answer

(A) no change in capacitance by connecting to a battery,

C_new / C0 = 1 ..........Ans

(b) deltaV = Q / C

C - is same and Q_new = 4 Q0

so V_new / V0 = 4 ............Ans

(C) C = e0 A / d

A = 4A0 then C = 4 C0

C_new / C0 = 4 .....Ans

(D) V = Q / C = Q0 / 4C0 = V0 / 4

Ans: 1/4 Or 0.25

(E) C = e0 A / d

d = 4 d0

the C = C0 / 4

C_new / C0 = 1/4 Or 0.25

(F) V = Q / C = Q0 / (C0/4) = 4 Q0 / C0 = 4 V0

V / v0 = 4 ....Ans
