What is a parallel connection of capacitors ? Obtain the formula for the effectivecapacitance in the parallel combination of two different capacitors. |
Answer» Solution :Two capacitors is arranged as in figure is known as parallel connection. Two capacitors of capacitance `C_(1)` and `C_(2)` is JOINED as shown in figure. In this connection, the same potential difference is applied across both the capacitors but the plate charges on each CAPACITOR are different. Hence, TOTAL charge, `Q=Q_(1)+Q_(2)` but `Q_(1)=C_(1)V,Q_(2)=C_(2)V` `:. Q = C_(1)V+C_(2)V` `:. (Q)/(V)=C_(1)+C_(2)` But `(Q)/(V)` is the effective capacitance of two capacitors joined in parallel. `:. =C_(1)+C_(2)` |
