Question

Five capacitors of $10\mu F$capacity each are connected to a d.c. potential of $100\mspace{6mu} volts$ as shown in the adjoining figure. The equivalent capacitance between the points $A$and$B$ will be equal to

• A. $40\mu F$
• B. $20\mu F$
• C. $30\mu F$
• D. $10\mu F$

Answer 1

Answer: (D)

$10\mu F$

Answer 2

In the given system, no current will flow through the branch CD so it can be removed

Effective capacitance of the system

$= 5 + 5 = 10\mu F$
