MHT CET · Physics · Alternating Current
A current of 5 A is flowing at 220 V in a primary coil of a transformer. If the voltage produced in the secondary coil is 2200 V and \(50 \%\) of power is lost, then the current in the secondary coil will be
- A 2.5 A
- B 5 A
- C 0.25 A
- D 0.025 A
Answer & Solution
Correct Answer
(C) 0.25 A
Step-by-step Solution
Detailed explanation
\(P_p = V_p I_p\) \(P_p = 220 \, \text{V} \times 5 \, \text{A} = 1100 \, \text{W}\)
