Question

The capacitors, each of 0.30 μF capacitance are star connected to form a capacitor bank. The capacitance of each arm of an equivalent delta connected capacitor bank is
1. 0.30 μF
2. 0.90 μF
3. 0.10 μF
4. 0.33 μF

Answer 1

Correct Answer - Option 3 : 0.10 μF

As all three capacitors are of same value, the value of each arm of delta connected capacitor bank will be one third value of each arm of star connected capacitor bank. Hence the each arm of an equivalent delta connected capacitor bank is, 0.10 μF.
