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.
how the direction of friction is obtained?
The voltage drops across two components when connected in series across an a.c. supply are v1 =150sin 314.2t and v2 =90sin(314.2t -∏/5) volts respectively. Determine (a) the v
