Equivalent Star Value of Capacitances Connected in Delta

When three capacitances, each of C/3 Farads, are connected in delta, we need to find their equivalent star value. The equivalent capacitance in star (C_s) can be calculated using the formula:

C_s = C_d/(C_a + C_b + C_c)

where C_d is the delta capacitance and C_a, C_b, and C_c are the individual capacitances connected in delta.

Step-by-Step Solution:

Step 1: Given that each capacitance is C/3 Farads.

Step 2: To find the delta capacitance (C_d), we need to calculate the sum of all three capacitances connected in delta.

C_d = C_a + C_b + C_c

Substituting the given values, we have:

C_d = (C/3) + (C/3) + (C/3)

C_d = C

Step 3: Now, we can substitute the values of C_d, C_a, C_b, and C_c in the formula for the equivalent star capacitance (C_s).

C_s = C_d/(C_a + C_b + C_c)

C_s = C/(C/3 + C/3 + C/3)

C_s = C/(3C/3)

C_s = C/C

C_s = 1

Step 4: The equivalent star value of the three capacitances connected in delta is 1 Farad.

Conclusion:

The correct answer is option 'B' - C. The equivalent star value for each capacitance connected in delta is C.
