A transformer is used to light a 24volts,70watts lamp from a
240a.c main.The current in the main cable is 0.35A.
Calculate,
(1) The efficiency of the transformer.
(2) the current in the lamp.
what happens if dc supply is given to the transformer?
Why there is restriction to generated voltage to certain limit for example (now 18kv) ?
