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, isNEET 2024 (Re-NEET)

Options:

Answer:

Solution:

In secondary circuit, $P = Vi$ $\Rightarrow 88 = 11000 i$ $\Rightarrow i = \frac{88}{11 \times 1 0 ^{3}} = 8 \times 1 0^{- 3} A$ $\Rightarrow i = 8 mA$
