The equivalent capacitance of the combination shown is: (a) C/2 (b) 4C (c) 5/3 C (d) 2C

Answer: (d). The right vertical wire joins the top and bottom rails, so both vertical capacitors have both plates at the same potential: shorted. The top and bottom C then both join the left terminal to the right terminal: parallel. Ceq = C + C = 2C So the answer is (d) 2C.

Combination of Capacitors

The equivalent capacitance of the combination shown is:

Show answer and solution

Answer: (d)

The right vertical wire joins the top and bottom rails, so both vertical capacitors have both plates at the same potential: shorted.
The top and bottom $C$ then both join the left terminal to the right terminal: parallel.
$C_{eq} = C + C = 2C$
So the answer is (d) 2C.
