Two capacitors of capacitance 600 pF and 900 pF are connected in series across a 200 V supply. Calculate (i) the effective capacitance of the combination, (ii) the pd across each capacitor and (iii) the total charge stored in the system. |
Answer» Solution : `C_(eff) = (C_1C_2)/(C_1 + C_2)` ` = (600 xx 900)/(600 + 900) = 540000/1500` `C_(eff) = 360 pF` ` Q = CV = 360 xx 200` `Q = 72 NC` `V_1 = (Q)/(C_1) = 120 V` `V_1 = (Q)/(C_2) = 80 V` |
