True or false

1-The power is transferred by induction and conduction in autotransformers

2-No load current in a transformer leads the voltage by about 70° - 80°

3-The efficiency of a two‑winding transformer for the same output compared to an autotransformer is smaller

4-The shell type of single phase transformer has single magnetic circuit

5-During short circuit test of a transformer, primary is supplied rated voltage
