Obtain the equivalent resistance R., for the circuit shown, and use it to find current i and power supplied by the 120 V source. Start by applying a wye-delta transform on the 5, 10, and 20 ohm wye. Then use series-parallel simplifications to get Ra. Please be sure to make separate drawings of your intermediate circuits and explain your steps carefully. Hint: Two of the delta resistances are 35 and 17.5 Ohms. The power is -1495 W. 12.5 2 102 52 120 V 30 2 15 2 20 2 ww ww ww
