Your TV's screen uses 4800 (V) of voltage to operate. To provide 4800 (V), inside your TV there is a transformer that converts wall outlet of 120 (V) to 4800 (V) reaching to the TV screen. The secondary coil of this transformer has 9200 turns. Your TV's screen connected to secondary coil of transformer uses 240 (W) of power. A) Calculate current in secondary coil. B) Is this transformer a step-up or a step-down...
