  1. Back to the Bridge • Which resistors are in series? • Which resistors are in parallel? ECE 201 Circuit Theory I

  2. Delta (Δ) Connection • Resistors R1, R2, and Rm (or R3, Rm, and Rx) are in a Delta (Δ), or pi (π) connection. ECE 201 Circuit Theory I

  3. Wye (Y) Connection • Resistors R1, Rm, and R3 (or R2, Rm, and Rx) are in a wye (Y), or tee (T) connection. ECE 201 Circuit Theory I

  4. Δ – Y Conversion ECE 201 Circuit Theory I

  5. Δ – Y Conversion (continued) • The resistance between the terminal pairs must be the same for both circuits ECE 201 Circuit Theory I

  6. Δ – Y Conversion (continued) • After some algebraic manipulation ECE 201 Circuit Theory I
