Using Delta to Wye or Wye to Delta transformation to determine: a. Current \( I_{s} \) (Hint: Redraw the circuit with a \( Y \) (Wye) configuration) in Figure 5.1. b. Current \( I \) (Hint: Redraw the circuit with a Delta configuration) in Figure 5.2. c. The equivalent resistor \( R_{a b} \) in Figure 5.3. Figure \( 5.1 \) Figure \( 5.2 \)
