Diode is a rectifier ...
which allow positive cycle of AC current to pass through it
and block negative cycle.. Bridge Rectifier made of 4 Diodes
is used to convert AC to DC....

Answer / naeem anwar

diode is an electronic device,which allow current to flow
only in one direction.........

Answer / anil kumar

diode is nothing like a switch,which conducts the electromnic current depending on the semi conductor charactoristics

Answer / khalid mehmmod

A semiconductor in which current flow in unidirectoin are know as diod.

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
