Topic: Network Theory

The equivalent capacitance across 'ab' will be (a combination of five 0.1 uF capacitors)

  • A. 0.2 uF
  • B. 0.1 uF
  • C. 0.5 uF
  • D. 0

Answer: B. 0.1 uF

Explanation: The capacitors are arranged in a bridge structure. Because all capacitors are identical (0.1 uF), the bridge is balanced. The capacitor in the middle branch can be removed, reducing the circuit to two parallel branches each containing two series capacitors, yielding an equivalent capacitance of 0.1 uF.
