A step-down transformer connected to an ac mains supply of 220 V is made to operate at 11 V, 44 W lamp. Ignoring power losses in the transformer, what is the current in the primary circuit?
Text Solution
Verified by ExpertsThe correct answer is:
NOT AVAILABLE
V p =220V V 3 =11V P = 44 W
As it is an ideal transformer
V p i p =V s i s =44W
220 x i p =44
i p = 
= 0.2A
