A 4 F capacitor is connected in series
with an 8
F capacitor. The combination is
connected across a 12V AC supply. The p.d. across the 4
F and 8
F capacitor respectively will
be
The answer is :- 3 The voltage will divide across the two
capacitors according to their reactances. The The 4 F capacitor will have twice the
reactance of the 8
F capacitor. For any particular
current taken, the p.d. across the higher reactance will be
twice that across the lower reactance, thus when the total p.d.
= 12V, the p.d. across 4
F capacitor = 8 V and the p.d.
across the 8
F capacitor = 4 V
