In a television set the power needed 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 91 W, and there is 5.5 mA of current in the secondary coil of the transformer to which the tube is connected.

a. Find the current in the primary.

b. Find the resistance of the secondary coil and the resistance of the primary coil. [4]
