Question
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 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
In secondary circuit, P=V i 88=11000 i i= 88 11 10^3 =8 10^ -3 ~A i=8 ~mA
