Determine a single-phase transformer, Physics

Assignment Help:

A single-phase transformer has 2400 turns on the primary and 600 turns on the secondary.

Its no-load current is 4A at a power factor of 0.25 lagging.

Suppose the volt drop in the windings is negligible, measure the primary current and power factor when the secondary current is 80A at a power factor of 0.8 lagging.
