Type: MCQ-conceptual-Medium-Class 12
A step up transformer is connected to an ac mains supply of 220 V to operate at 11000 V, 88 watt. The current in the secondary circuit, ignoring the power loss in the transformer, is
A
8 mA
B
4 mA
C
0.4 Å
D
4 Å
Correct Answer
Option A
Detailed Explanation
The power in the secondary circuit is the same as in the primary circuit. Using P = VI, the current I = P/V = 88/11000 = 0.008 Å or 8 mA.
