Determine the primary current and power factor, Physics

Assignment Help:

A single-phase transformer has 2000 turns on the primary and 800 turns on the secondary.

Its no-load current is 5A at a power factor of 0.20 lagging.

Assuming the volt drop in the windings is negligible,

Determine the primary current and power factor when the secondary current is 100A at a power factor of 0.85 lagging.
