In a television set the power essential to operate the picture tube comes from the secondary of a transformer. The primary of the transformer is connected to a 120-V receptacle on a wall. The picture tube of the television set uses 82 W, and there is 5.5 mA of current in the secondary coil of the transformer to which the tube is connected. Find the turn’s ratio Ns/Np of the transformer.
