Two capacitors are charged individually to potential 80 V and 100 V , respectively. They can store charge 20 upto `muC` and `30 muC` respectively. Find the ratio of their capacitances. |

Answer» (i) `C = theta//V` `C_(1) = theta_(1)//V_(1)` `C_(2) = theta//V_(2)` (ii) `C_(1) : C_(2) = (Q_(1))/(Q_(2)) xx (V_(2))/(V_(1)) = 2/3 xx 100/80 = 5/6` `C_(1) :C_(2) = 5:6` |
