NEET2024PhysicsAlternating CurrentActual
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
Options
- A8 mA
- B4 mA
- C0.4 A
- D4 A
Correct answer
A. 8 mA
Step-by-step solution
In secondary circuit, P=V i 88=11000 i i= 88 11 10^3 =8 10⁻³ ~A i=8 ~mA
