please answer both subparts i will like for both

Extracted text: a. A single-phase transformer rated at 400 /230 V at 10 kVA has 200 V placed across the primary winding, and a short circuit placed across the secondary winding. State whether, or not, the core of the transformer will saturate. A power company in Norway wishes to provide electricity to Sweden, via three-phase ac transmission. The equivalent transmission circuit for one phase is shown in Fig. 3. State how real power can be transmitted, while keeping the voltage at the receiving end (VR), at a desired level, without changing the line impedance (X), or the magnitude of the voltage at the sending end (Vs). This is Fig. 3 jXL Vs 28 ZR VR Z0
