True or false

1-The secondary winding of current transformer is always kept close

2-The imaginary component of no load current Io is responsible for generation flux Φ in transformer

3-The efficiency of a transformer at load 0.8 p.f. Lag is same at load 0.8 p.f. Lead

4-The emf induced in the primary of a transformer lags the flux by 90 degree

5-The flux which escapes the core and links only with one of the transformer winding is called mutual flux
