Charge in Bridge NetworkHardQuestion 31536

Question

Five capacitors of 2 μF each are arranged like a Wheatstone bridge with a 12 V source. If bridge is balanced, equivalent capacitance seen by source is:
  1. A
    2 μF
    Correct
  2. B
    1 μF
  3. C
    4 μF
  4. D
    5 μF

Correct answer

2 μF

Explanation

With balanced bridge, central cap is removed. Remaining two pairs (each 2 μF in series) are in parallel: each series pair = 1 μF, parallel total = 2 μF.
