Question

The charge on $3\mu F$ capacitor shown in the figure is.

• A. $2\mu C$
• B. $10\mu C$
• C. $6\mu C$
• D. $8\mu C$

Answer 1

Answer: (B)

$10\mu C$

Answer 2

: Since all the capacitors are connected in series,

$\therefore$ Equivalent capacitance is

$\frac{1}{C_{eq}} = \frac{1}{2} + \frac{1}{3} + \frac{1}{6} = 1\therefore C_{eq} = 1\mu F$

Charge on each capacitor is same ($\because$V = 10 V)

$q = C_{eq}V = 1 \times 10 = 10\mu C$
