by

Electrical Engineering multiple choice questions on Delta to Wye conversion.

Circuit 1

In circuit above the formula for Rx is defined mathematically:

  1. Rx = R1/(R1 + R2 + R3)
  2. Rx = R2.R3/(R1)
  3. Rx = R2.R3/(R1 + R2 + R3)
  4. Rx = R2.R3/(R2 + R3)

Correct answer: 3. Rx = R2.R3/(R1 + R2 + R3)
