A) 1.26 k? B) 126 ? C) 1.26 ? D) 126 k?

Answer the following statement true (T) or false (F)
Answer the following statement(s) true (T) or false (F)
1. Supplying reactive power locally leads to increased line current, thus increased line losses. 2. When a three-phase system is delta-connected, the phase currents equal the line currents. 3. Excepting a few small isolated systems, the electric grid in North America consists of a single large 4. synchronous 60 Hz system. 4. The total real power losses of an ideal transformer are always zero. 5. Transposition of high voltage transmission lines, particularly those operating at over 345 kV, is practically always done on every transmission line to keep the system blanced.
