A current of is flowing at in the primary coil of a transformer. If the voltage produced in the secondary coil is and of power is lost, then the current in the secondary coil will be:
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given: Voltage in the primary coil Vi=220 V, voltage in the secondary coil VO=1100 V, current in the primary coil, Ii=6 A, Power lost=40% Let the current in the secondary coil be IO and η be the efficiency of the transformer. Efficiency η=POUTPIN Then,…
